A couple of silent screen "names," Edmund Burns and Molly O'Day flounder badly in this penny-ante shipboard melodrama from Poverty Row producer Larry Darmour. Second-billed Burns plays Richard Charters, a young man imprisoned for a murder he didn't commit. Escaping, Richard dons a beard and while hiding out in a dockside dive overhears a plot to steal a sunken treasure after it had been salvaged by Captain McCall (James Donnelly). After a chance meeting with the captain's flirtatious daughter, Ann (star-billed O'Day), and her pet monkey, Richard stows away on McCall's ship. His presence, however, is revealed when he comes to the rescue of Ann, who is being mauled by Johnson (Walter Long), the villainous first mate. Although cornered by the crooks, Richard manages not only to save the day for Captain McCall and Ann but also catch the villain, Killer Lundgren (William F. Moran), who sent him to prison in the first place.
