Stella (Lacey Turner) is in deep trouble. Summoning the girls home with a "Switch” text, she’s desperate to cast a spell to save her skin. Hannah (Hannah Tointon) flies home from India, Jude (Nina Toussaint-White) abandons customers in work while Grace’s (Phoebe Fox) romantic encounter is interrupted. With chaos under control and buoyed by initial success, Stella’s confident enough to stand up to her boss, Janet (Amanda Drew). She gets sacked. The Witches of Camden cast another spell, but rusty after months of being apart, it results in a magical race against time to undo their own mistakes. When Grace’s mum, Gloria (Caroline Quentin), turns up out of the blue Grace is forced to cut the apron strings or be a mummy’s girl forever. Meanwhile commitment-phobe Hannah must choose between life on the road or life with her coven.

The Witches of Camden have been hexed. Confronting their arch nemeses, the posh Witches of Kensington, isn’t easy but a few champagne cocktails later the two covens seem the best of friends. However, when Hannah (Hannah Tointon) tries to get a job at Stella’s (Lacey Turner) workplace it seems that bygones are far from bygones. Grace (Phoebe Fox) needs some help getting ready for her date with Joel (James Rastall) – but will he give her that magic feeling? Jude’s (Nina Toussaint-White) wishes for a new boss are answered when Gerry (Jamie Davis) turns up – but is he too hedonistic even for Jude? And when the girls try to get retribution on the Witches of Kensington there are disastrous consequences to their actions.

Stella (Lacey Turner) hasn’t had a date in years. In fact, she’s not fancied anyone in years. The girls are forced to confess that they cast a spell years ago to help her forget an ex-girlfriend. But not getting over Lucy (Rosamund Hanson) has stopped Stella from moving on. Stella must be re-introduced to nightmarish Lucy and find peace with their past relationship. Unfortunately, Stella falls in love with Lucy again. The girls must watch as the destructive relationship threatens to destroy not only everything Stella has worked so hard for, but also their precious coven. Meanwhile, Hannah (Hannah Tointon) gets into a spot of bother with a new career choice, Jude (Nina Toussaint-White) encounters problems when she takes a short cut to the top of her career ladder, and is Grace (Phoebe Fox) in love with Jude’s (Nina Toussaint-White) boyfriend?

The girls’ coven of anniversary is approaching, and preparations for celebrations are in place. But when Grace (Phoebe Fox) gets mugged, she wants to leave London for good. The girls do the only thing they think will help – they cast a confidence spell to help Grace cope with city life. Stella (Lacey Turner), meanwhile, has problems of her own when India, one of their nemeses from the Witches of Kensington, turns up to work at the PR Agency. Intent on destroying Stella’s career and the company with it, India casts a charm on the whole office. Hannah (Hannah Tointon) enjoys being market holder on a stall of Jude’s (Nina Toussaint-White) designs, until all the stock is stolen. All in all, things don’t look good for a happy celebration. But there are darker forces at work and things soon get out of hand.

Grace (Phoebe Fox) and Gerry’s (Jamie Davis) relationship seems to be blooming nicely. Having just split up with Gerry herself, Jude (Nina Toussaint-White) is feeling weird about this. When she calls Mike (Kevin Bishop) over, she’s looking for some no-strings comfort sex, but she gains so much more. Hannah (Hannah Tointon) takes up tutoring with a little magical twist and gains Tuppence (Lilly Lucia Ainsworth) – a privileged, precocious and pretty lonely pupil. Grace’s anxiety levels reach fever pitch when she becomes convinced that Gerry doesn’t like her as much as she likes him. Stella (Lacey Turner) is set on finding her one true love through efficient means. When things inevitably go disastrously wrong, it’s time to reach for that spell book!

It’s the Summer Solstice and the girls go to Grace (Phoebe Fox) and Hannah’s (Hannah Tointon) hometown of Lower Sooth to celebrate. Hannah is disappointed when her mum, Esme (Imogen Stubbs) is nowhere to be found, Grace is shocked when Gerry (Jamie Davis) turns up despite them casting a spell so that he wouldn’t and Jude (Nina Toussaint-White) is looking forward to a bit of excitement in the forest with her first love, Jack (Howard Charles). But these are the least of their concerns when the Witches of Kensington arrive – with Alexa’s mother, Karina (Diana Kent) in tow. This super-coven is set on bringing the Witches of Camden down. Before the longest night of the year is out, there is a scandalous showdown to survive and some shocking home truths to be shared.
