High society jockey/playboy Larry Sturgis (John Darrow) is preparing to marry Mary Vernon (Mary Brian) but then is wrongly convicted of murder on the eve of the wedding.
He manages to escape and sets off in pursuit of the real murderer... to Monte Carlo (of course!) There he befriends a French woman (Yola d'Avril) and seeks the murderer who he knows is a gambler who plays certain numbers on the roulette table...
Quite a lot of story to fit into a fairly short film them and it is rather break-neck at times, maybe a bit too fast at points of the film as it can become a bit confusing. Such as why exactly does the police inspector (George Hayes) think Larry is innocent and how does an escaped con manage to get to Monte Carlo with the police on high alert? Once the film gets going though its a winner, unlike Larry who fell off his horse at the start!
