Right after a husband and wife (Robert Edeson and Eulalie Jensen) arrive home from their honeymoon, the husband goes to fetch his sister from boarding school. While he is away, the wife's friend and neighbor, McGregor (Harry Morey), invites her to a party, and she accepts. On the way back home, they're involved in an accident, and McGregor takes the wife, who's unconscious, to recover at a nearby roadhouse. Unfortunately, McGregor's coke fiend brother (William R. Dunn) is there partying, and he threatens to put a seamy spin on the innocent situation and tell all. This bit of blackmail comes in handy when he becomes the husband's secretary and decides that he wants the sister, who McGregor himself comes to love. The husband begins to suspect that something is going on between McGregor and his wife, as does the sister. But when the addict is discharged, he shows his true nature by trying to shoot the husband. He wounds the sister instead when she comes between them. While trying to escape from the police, he finally kills himself, so the husband, wife, McGregor, and the husband's sister are left in peace.
