Thunder Afloat

In a New England port town, Pop Thorson (Wallace Beery) and Rocky Blake (Chester Morris) are rival tugboat owners. Thorson's boat has sunk in the shallow water while docked, and he is certain Blake sabotaged it to keep Thorson from winning a lucrative contract to move barges of military supplies. Thorson is a widower who built his own tugboat and lives on it with his adult daughter Susan (Virginia Grey). She loves her father, but also likes Blake (who denies the sabotage) and does not want the two men to fight.
