Plot
Garry is a racehorse owner. After he loses money at the races, his fiancee Wenda jilts him and marries Lord Willis Panniford, whose sister Molly trains Garry's horses.
Whilst drowning his sorrows, Garry becomes involved in a big-race scandal. The plot is to steal his own prize horse before a race, therefore increasing the odds in another big upcoming race, the Ascot Gold Cup.
Stewards run an inquiry into the running of Garry's horse. Wenda is called as a witness. She denies that Garry's first telegram telling her not to back his horse was cancelled out by another message from him, which was sent before the race.
