Kath Day is enjoying life as an empty nester until her recently married daughter Kim moves back in. To Kim's disgust, Kath has a lover and they're going for it like rabbits. Kath has a feeling in her waters that Kel is about to make their sensual relationship a mere formality. Kim enlists Sharon's help to stalk her estranged husband Brett, with disastrous results.

Brett's relationship with a 75kg Rottweiler by the name of Cujo has Kim's nose out of joint. She's out to sow her rolled oats and, with encouragement from Sharon, they go speed dating at the local pub. Meanwhile Kath is concerned that there is a dark secret at the heart of Kim and Brett's separation, one that even threatens her future with Kel.

Wedding preparations for Kath and Kel's big day are well underway. Kel puts his skills as a fine purveyor of meat to the test as he begins to design a commemorative sausage for the connubials. The future of the Sharon's netball team and three generations of family history are at stake when players drop out at the last minute. Can Kim drag her manicured nails off the couch to help her second best friend in need?

Kath's wedding plans are thrown into chaos when she discovers that Kim has really stacked on the weight and doesn't fit into her bridesmaid's dress. Sharon discovers self-help and motivational books and considers marriage counselling as a career. Her reading is soon put to the test as a complete breakdown of all relationships erupts. A round table counselling session produces startling revelations, but talk to the face cos the hand ain't listening!

Kath's flat out organising the wedding and the stress is starting to show. Comments about her looks are making her worry that Kel is losing interest. When Kel stands Kath up one too many times, Kath is determined to move on without him. Meanwhile Brett's in the freezer while Kim plays ice maiden. Treat 'em mean, keep 'em keen is Kim's motto but Sharon puts an ice pick in the works.

Kath is scrimping and saving money to pay for the ritziest fairytale-style wedding on her own. After gambling and competitions fail to raise the much-needed cash, Kath organises a lingerie party with Kim and Sharon modelling the merchandise and serving hot suggestions. Kim discovers something she's really good at, internet chat rooms and online shopping with Kath's credit card. With the help of a modem, Kim is determined to meet the man of her dreams. Beware the lace snap crotch teddy!

Kath Day's wedding is weeks away and Kim organises a top hens night. With a stick on bra, fake tan and a one-sleeved top, Kath is ready to party. However things go horribly wrong when they unwittingly imbibe some illicit substances. And then there's Kel's Buck turn, but don't go there girlfriend.

The day of the ritziest fairy tale wedding has arrived. With punch served from the rubbish bin and a tarp over the clothesline, the guests arrive at 4.45pm for a 4.46pm start. A unique chain of events leads to a nuptials that no one will ever forget, well not quickly anyway.

Kim Craig nee Day's marriage is still up the proverbial and newlywed Kath Day-Knight's libido has gone awol. They both look deep inside their chasms and think outside the box with some very positive results.

Although Kel is getting right up Kath's goat - literally - they find they still have some marital niggles to iron out. Brett has finally popped the ""R"" word and Kim's head is filled with nothing but silly putty.

Look out peoples! Kimmy is bored. Brett is working forty eight hours straight, Sharon has a new best friend and Kath is in the roof looking for her vanity. Will Kimmy succumb and go to the stupid school reunion? If so what will she wear?

Kath and Kel's new eating plan is leaving them totally shagged but not in the way they would like. Unlucky in love Sharon decides to take positive steps to improve her vavavavoom. Meanwhile Kim is helping Brett on his career projectory.

It's on! Sharon has a boyfriend and pash rash 24/7. Kim and Brett's marital issues come to a head whilst shopping in IKEA. Kath has the inkstinks for floral designs.

Kath and Kel are rattling around in that big house and Kath thinks Kel has genes to die for. Kim becomes gropable when Brett won't talk about his privates. Sharon has a calling.

Kim doesn't give a fat rats that Tina isn't coming to the baby shower as long as she drops off a present. Kath's head is screwed on backwards when Kel's mate Sandy Freckle arrives.

Brett's got to be at Computacity Maribynong for the grand opening and misses Kim's labour. Kim gets a rude shock and everyone's past catches up with them.

Like her wine time nuts, Kath's feelings are mixed at this late stage when Gary arrives back to stake his claim. Kel is hamstrung as Gary has Kath over a barrel. Meanwhile, Kim is loving herself sick as a new mum. She is blown away at how gross Epponnee's motor skills are. Ditto Brett.

With their fascinators on and Fleur De Lys Picolos in hand, Kath and Kim hit the races. They mingle with celebrities (C-list), while Sharon gets lucky with a very little racing identity. Brett has a reality check when he babysits lil' Eps. Meanwhile, Kel is up to his eyeballs in lamb flaps and honey soy drumettes.

Kim counts her chicken feet before they hatch as a family crisis takes Brett and Epponnee to the Gold Coast. Meanwhile, Kath feels that she and Kel have been too into each other - you know, physically - and they decide to spread their wings (socially that is).

Kimmy kicks up a major stink in her bid to trim down as Sharon discovers her inner fascist at Boot Camp. Meanwhile, Kel's palm pilot is up to pussy's bow, but Kath can't find a window.

Hooray! Sharon's got a date. Kim gives Sharon a major makeover and all fingers are crossed. All stops are out in a nail-biting sequence when Kath and Kel try to update their home theatre system (I mean it is almost three years old). Meanwhile, Brett gets on Kel's wick.

Kim has always seen herself in a cul-de-sac, but Brett has bigger plans. His exciting news means Kim has to pull her considerable weight financially. Ditto Kath, whose new career venture has her stimulated big time, and that is good for everyone. As per usual, Sharon drives everyone mad.

Fifty is the new forty in the Day-Knight household, and Kath plans a celebration for Kel and pulls out all the stops for a Nibbles to end all Nibbles. Meanwhile, the jury is still out on Sharon's godmother status, and Kim gets holier than thou. Brett has an epiphany on a Buckin' Bronco.

Look at moi! Look at moi! Look at Kylie! International pop icon Kylie Minogue makes a special guest appearance at Lagoon Court. Meanwhile, what is to become of Kath and Kel, after Dr Ng tells them to go fat free? Kim and Brett are at loggerheads over Epponnee's career projectory. The clock ticks loudest for Sharon as she waits in the wings like a white ant.

To try and re-invigorate his marriage, Brett decides a romantic trip away to tropical Queensland could be just what is needed. Elsewhere, Kath is feeling flat and Sharon is accused of the greatest sporting crime of all.

Epponnee-Raelene Kathleen Darlene Charlene Craig is turning one so it’s party time at Lagoon Court. Kim is sparing no expense to make sure Epponnees party is going to blow everyone out of the water. Kel has some celebrating to do as winner of a prestigious award. Guest starring Eric Bana and Rob Sitch.

Kath becomes a health professional and has the TAFE certificate to prove it. Elsewhere, Kim needs a guinea pig for her new career...and Brett is busting to impress his bosses.

Education wise Kim would like Epponnee to go private... just for the status of it; and Kel is looking forward to giving his jerbras a good watering.

The down stairs toot is blocked and Kath & Kel's ensuite gets a workout. Next-door neighbour Mandy's house is up for sale and Kel puts in an offer (well over the reserve). Meanwhile, Sharon & Kim put their smarts on the line when they go on 'Deal.' Guest starring Andrew O'Keefe.

Kel is desperate to find out if he's a nob with noble blood. Kath finds a family skeleton in her closet (well her walk in) and Sharon comes face to face with a long-lost relative from the other side of the world. Guest starring Matt Lucas (Little Britain) and Stephen Page (Bangarra Dance Theatre).

Sharon has sworn off guys and has been celibate for three months. Brett is up to his old tricks and Kim kicks him out (again) but when Sharon buys Brett a foot long from Subway it's on for young and old. Kath is also one frustrated lady with Kel busy pushing buttons that are not hers.

Sharon's always been unlucky in love, until now that is, Kath and Kim go into planning mode for the event of the century! Brett gets the job of a lifetime and finds a perfect new place to live with Kim and Epps. With the house to themselves Kath and Kel embark on a new business venture and being people's, people there is no way they cannot fail. Looks like it's all going to end happily for everyone...Or is it?
