Three of the Sharks go in on a deal together for an innovative internet company with two brothers from Brazil (Rodolfo and Alexis Saccoman, who now live in Palm Beach, Florida and San Francisco, California, respectively). But just before the deal is sealed, a battle ensues and one of the Sharks is ousted. An eccentric, life-long entrepreneur named Cactus Jack (aka Jack Barringer from Ames, Iowa), who has never had a regular job in his life, comes to the Shark Tank in order to get an investment for his latest fitness device, but he must make a huge, personal sacrifice if he wants to do business.

When her first opportunity at pitching the Sharks couldn't happen because of devastating news right before her appearance, this charming housewife from Charleston, South Carolina gets another chance and hopes to secure a deal this time around. She sends the Sharks into a feeding frenzy, but Barbara Corcoran -- the only female Shark - thinks her colleagues are behaving like smitten teenage boys rather than savvy business investors. Also, Kevin O'Leary is determined to seal a deal with a college student from Bloomington, Indiana who pitches a product made from soy that he concocts in his mom's kitchen. But the young entrepreneur's idealism and naiveté may get in the way of a deal.
