Being the chairman and CEO of multibillion-dollar corporation Camping World takes up a lot of Marcus Lemonis' time. But when he's not running the company, he's searching for struggling businesses in need of cash. Lemonis tries to help turn each company around by offering cash for a piece of the business and a percentage of the profits. Now he's bringing that process to TV with this series, in which he puts millions of dollars of his own money on the line. Once he's working with the company, he does whatever is necessary to save the business and make a profit for himself -- even if it means firing the president. Although some of his changes could be considered radical, the companies should be willing to go along with them because in the last 10 years, Lemonis has successfully turned around more than 100 companies. To quote the not-so-humble Lemonis, "When I have skin in the game, my way is the only way your business will survive."

"Adventure Capitalists" can succinctly be described as "Shark Tank" for outdoor enthusiasts.

If the tests are successful, the potential backers can choose to make a large investment in each product. The investors who have the option to change the entrepreneurs' lives include former NFL player and TV host Dhani Jones, former Olympic skier Jeremy Bloom and American gymnast and Olympic gold medalist Shawn Johnson East.

Self-made millionaires Mike "Rooster" McConaughey -- brother of Oscar-winning actor Matthew -- and Wayne "Butch" Gilliam made their fortunes deep in the heart of Texas.
