For the first time, an entrepreneur who walked away from a deal returns to the Tank and is given another chance at the American dream. During the revived negotiation that started in Season 2, James Martin from The Dalles, OR phones Jim Koch, co-founder of Samuel Adams beer, for advice on the Sharks' latest offer to invest in Copa Di Vino, a plastic wine-in-a-cup business.

Also, a versatile inventor from San Antonio, TX must prove to the Sharks the waste products created by his 100-foot tall generator can be transformed into gold; a housewife from Kokomo, IN wants the Sharks' help to grow her handcrafted cookie company into a household name; and a former medical student from Penfield, NY makes T-shirts where a motivational message appears when activated by sweat.
