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."

Since launching "The Profit" in 2013, serial entrepreneur Marcus Lemonis has expanded his portfolio of businesses significantly, having invested in a number of companies on the series. Now, he's searching for a partner who can help him manage his rapidly expanding empire. To find that person, Marcus is sticking with the same format that has led to his business expansion: a reality show. Although thousands of hopefuls from across America applied for the position, only 10 people have been invited to Chicago to take part in the final interview process, which plays out over the course of five episodes of "The Partner." At stake for the contestant who ultimately emerges victorious is the aforementioned role with Lemonis' company, which includes a $500,000 contract and an equity stake in the enterprise. Lemonis says he is looking for someone with the same drive and passion as the entrepreneurs with whom he has partnered.

The "one percent" has become a synonym for America's very wealthy. The upper echelon of that already-elite group -- per this show -- is the "filthy rich." Each half hour spotlights how the latter spend: lavish parties, expensive electronics, outrageous mansions, private islands. Billionaires featured include entrepreneur Charles Shaker, who had a $500,000 bar tab in Monte Carlo; business magnate Mukesh Ambani, whose house -- valued at $1 billion -- may be the world's largest; and Oracle co-founder Larry Ellison, who bought a Hawaiian island for nearly $500 million. Though extreme to most folks, these people have the money and aren't afraid to spend it.
