The trendy elegance of director Douglas Sirk's later big-budget soap
operas is nowhere to be found in Sirk's Atomic-Age melodrama Mystery
Submarine. MacDonald Carey stars as Brett Young, a U.S. undercover
agent whose job it is to prevent atomic secrets from falling into the
wrong hands. Marta Toren co-stars as Madeline Brenner, a woman of
mystery who is seemingly in cahoots with enemy agents. The film's
"maguffin" consists of the top-secret info stored within the brain cells of
scientist Adolph Guernitz (Ludwig Donath). The titular mystery submarine
figures into the film's climax, which takes place just off the coast of
Mexico.
