Submarine Patrol

Set during World War I, Submarine Patrol stars Preston S. Foster as a naval officer demoted for dereliction of duty. He is forced to commandeer a battered old submarine chaser and its ragtag crew. Anxious to redeem himself, Foster transforms his loser underlings into a crack combat team, chalking up numerous enemy sinkings. Richard Greene costars as Foster's junior officer, a rich wastrel who matures into a worthwhile individual during his tour of duty. Deftly directed by John Ford, Submarine Patrol was enthusiastically received by audiences and critics alike in 1938. (official distributor synopsis)
