Social-climbing Helen (Jean Muir) sends her less-pretentious younger sister Kate (Laraine Day) to a party in her stead, and there Kate strikes up a friendship with wealthy playboy Ridley Crane (Robert Cummings), but later, he clearly prefers Helen. One night he gets drunk, so Helen drives him home, but she accidentally kills a bicyclist then allows the crime to be pinned on Ridley. Kate learns who really was driving, but she cannot convince Helen to reveal the truth, and Ridley is sentenced to prison. ~ Bill Warren, Rovi
