Plot

Late one winter night, Swede rows up to a public dock in a dinghy. He hides when he spots a young woman who walks to the end of the pier. When a new night watchman (an uncredited Emory Parnell) notices her and fears she is about to jump, Swede stops him from bothering her. The sailor begins recounting her story, and the film segues into a long flashback.
