Based on the hit stage play, Running Riot is the big local release for this Christmas. After making a foolish bet, a playboy-type ropes his pal in to train him to take part in the Comrades marathon. His wife suspect he really wants to go to Durban to fool around, so she hires a private detective to keep an on him. In Durban, he meets and falls for a stunning Russian athlete, but her ex-KGB trainer also has his eye on her. One thing leads to another, and after the race, things come to a head as the competing lovers, coach, and private detective find themselves in compromising and complicated situations.
