Synopsis by Hal Erickson
Waterfront was the latest entry in First National's popular Jack Mulhall-Dorothy Mackaill series, and the first to qualify as a "sound" picture, even though its audibility was confined to a musical score and sound effects. Mulhall plays Breezy O'Connor, a womanizing sailor with a sentimental streak. Mackaill is Sadie Seastrom, a tomboyish waterfront lassie with a yen to sail the Seven Seas (she even wears a navy uniform in hopes that someone will get the hint). Sadie's ex-sea captain father (Knute Erickson) despises sailors, but takes a liking to Breezy when our hero expresses the wish to settle down on a farm. Captain Seastrom and Breezy conspire to discourage Sadie from her maritime yearnings by framing a fake kidnapping and a phony mutiny, but the plan misfires, and Breezy is obliged to rescue the heroine from a few genuine perils.
