Marcus Lemonis will do whatever is necessary, including guiding, firing and investing his own money, in order to save struggling companies. In return, he will become a partner and take part of the profits. Lemonis makes offers impossible to refuse: cash from the business and a percentage of the profit. And once inside these companies, he will do almost anything to save the business and make a profit; even if that means firing the president, promoting the secretary or doing the job himself.
