The Sea Beast is a silent screen adaptation of Moby-Dick featuring John Barrymore in action as Captain Ahab Ceeley. At the beginning of the story, Ahab and his step brother Derek (George O'Hara) compete for the affections of a winsome minister's daughter, Esther Wiscasset (Dolores Costello). Meanwhile, the albino whale has been eluding harpooners, and bears the scars of many failed attacks against him. His fame has reached epic proportions. One day, Ahab and Derek are on the same whaler as the whale moves into view. With the visual drama enhanced by the water and pitching boat, Ahab raises his harpoon to kill the beast. At that moment, Derek pushes him overboard.
