Marcus attempts to help two feuding brothers whose used-car business is weeks away from being shut down.

Despite generating all that cash, Planet Popcorn still can't show a profit. But serial entrepreneur Marcus Lemonis believes he can turn this business around and make Planet Popcorn a national brand. But to do it, he'll need this motley crew to follow his plan and prove they can be trusted.
