Crittendon Mariott's vivid story formed a wonderful basis for the atmospheric filmmaking talents of Maurice Tourneur. The "isle of lost ships," at least in Tourneur's interpretation, isn't an island at all, but a cluster of derelict ships, from ancient to modern times, floating together on a bed of sea-weed in the Saragosso Sea. Another ship wrecks and joins the others. Its passengers all manage to escape, except for three -- Frank Howard, an escaped convict (Milton Sills), Detective Jackson, who is bringing him back to justice (Frank Campeau), and Dorothy Fairfax, the daughter of a millionaire (Anna Q. Nilsson). The trio find that a group of about 50 roughnecks live among these ships, and their leader is Peter Forbes, a sea captain (the ever-villainous Walter Long). Forbes is determined to force Dorothy to marry him, but Howard battles for her. After Forbes meets his defeat, Howard weds Dorothy in name only and finds a derelict submarine amidst the wrecks. Since he is a naval engineer by trade, he is able to get it up and running once again and they make their escape. After all these heroics, it's clear that Howard is innocent of the murder of which he was accused, and he wins Dorothy's love. This picture was remade in 1929, as both a silent and a talkie.
