Undercover Billionaire: Comeback City

Self-made billionaire Glenn Stearns is called on to rescue Tipsy Bean, an Erie coffee shop with huge potential but suffering from a fatal flaw.

Glenn enlists a secret weapon to turn Erie entrepreneur Michael Hooks' multiple hustles and side gigs into a life-changing business empire.

Glenn calls on his friend Cat Cora to help save a 60-year-old Italian diner. The husband-and-wife owners must adapt to the times to keep the eatery alive.

Glenn teams up with Tae Bo inventor Billy Blanks to transform a struggling karate studio into a fully-fledged fitness empire.

Glenn returns to save a staple of Erie manufacturing that's fallen on hard times. To secure a big deal, he puts the owner through a salesman bootcamp.

Glenn takes on his biggest challenge yet: saving his own business, Underdog BBQ. Changes include new sources of revenue and a shocking decision.
