Victor Hugo's Toilers of the Sea was none too faithfully adapted for the screen as Sea Devils. The hero is Guernsey-Island smuggler Gilliat (Rock Hudson); the heroine is glamorous British spy Drouette (Yvonne de Carlo). Set during the Napoleonic wars, the plot finds Gilliat and Drouette trying to outsmart one another for the first few reels. Gilliat even kidnaps Drouette at one point, believing her to be in league with the hated French. Eventually, of course, Gilliat must rescue Drouette from the French, thereby preventing Napoleon's planned invasion of England. Shot on location, Sea Devils was directed with verve by Raoul Walsh.
