When Adam Hayward (Robert Montgomery) learns that Sam Baxter (Michael Ripper), a friend from England who risked his life to save Adam's in World War II, is accused of murder, Adam travels to England to prove Sam's innocence. While there are two witnesses to the crime, which Sam insists was self-defense, Adam has trouble locating one of them.
The reluctant witness, Sandy Summerfield (Ann Stephens), has reasons of his own for not wanting to come forward.
