High school sleuths Jackie Cooper, Bonita Granville and Gene Reynolds prove solving a murder is mere child's play in this fast-paced whodunit, costarring Gail Patrick and Ian Hunter. When his gambler father (Hunter) is wrongly convicted of murder, Johnny Davis (Reynolds) is determined to prove his dad's innocence. Following a series of clues that point to the real killer, Johnny and pals By (Cooper), Kate (Granville) and Doc (Leo Gorcey) decide to stage a play that will force a confession and drop the curtain on a murderer. Also starring Tommy Kelly (The Adventures of Tom Sawyer), Billy Watson (The Shop Around the Corner) and June Preisser (Strike Up the Band), Gallant Sons is "a satisfying, amusing and smartly paced mystery" (Bosley Crowther, The New York Times) featuring the most famous juvenile stars of the era.
