Fog Bound (1923)

A mutual attraction develops between Roger Wainright, a wealthy New York idler visiting his Florida estate, and Gale Brenon, daughter of a federal revenue agent. During a raid on a fashionable gambling resort, Mr. Brenon is killed, and suspicion is focused on Roger, who escapes to Gale's home. She helps Roger escape into the swamp but joins the search for him when she learns of her father's death. Gale weakens when she finds Roger, but he decides to surrender. Ultimately, Mildred Van Buren exposes Deputy Brown to be Brenon's murderer.
