After being dishonorably discharged for issuing a costly and fatal order, Colonel Loring Leigh (C. Aubrey Smith) gathers his four sons (William Henry, George Sanders, David Niven, Richard Greene) to prove his innocence as a conspiracy victim. But Leigh is murdered, his death disguised as suicide. Now his sons must find the guilty party and restore their father's integrity, while close behind their every move is Lynn Cherrington (Loretta Young), a woman in love with Geoffrey (Greene).
