A family-run BBQ restaurant in the tranquil town of Latta, South Carolina, is about to go up in smoke if Marcus Lemonis can't help them in time. Legendary Shuler's BBQ is a so popular that lines run out the door, but keeping up with the times is proving a bigger challenge than anyone expected.

In Pittsburgh, PA, husband-and-wife owners of a Greek sandwich shop chain have failing franchisees about to revolt. My Big Fat Greek Gyro has several dire changes needed to the way they do business, and Marcus might just be too late.
