Billionaire Glenn Stearns is determined to conceive and grow another million-dollar business from scratch in just 90 days in Erie, Pennsylvania.

Billionaire Glenn Stearns hits a breaking point that sends him to the hospital and threatens to shut down his mission to identify a new business and grow it to a $1-million valuation in just 90 days.

To fund his new company, Glenn gambles all the money he's earned so far on his biggest money-making scheme yet, but a major roadblock threatens to shut it all down.

Glenn doubles down on his million-dollar idea with a bold new plan to expand the business. But in the midst of making deals, Glenn's confronted with the prospect of losing all of his startup funds, leaving him fighting to keep the dream alive.

With his team depending on him, Glenn loses a critical deal and is sent spinning. As the pressure mounts, the underdogs rally to flip a house that could save the business and change their lives forever.

The Underdog BBQ team races to prepare for their opening day, but when Glenn accidentally reveals his true identity to a team member, it puts the entire business and the bet in jeopardy.

Glenn sinks everything into Underdog BBQ's big debut and first chance to make money. But before the cash register even opens, the team's plan goes up in flames, threatening the future of the company before the 90-day deadline.

Glenn's 90 days are up and it's time to find out if his business is worth a million dollars. But first, Glenn reveals his true identity to his team as well as what each one of them has earned for their part of Underdog BBQ.

With just $100 in their pockets, three business titans are dropped in unfamiliar cities, stripped of their names, money and contacts and given a simple challenge: build a $1 million business in just 90 days.
