San Diego private investigator Tom Hickey has traded in his fedora for an M.P. uniform. Though WWII is still raging in Europe and the Far East, things seem quiet for Tom at the Tijuana border. At least until farm boy Clifford Rose enlists Hickey to help rescue his emotionally traumatized sister Wendy from a sordid Tijuana night club. But when Tom finds Wendy enmeshed in a Nazi plot against the U.S., he's unsure if he, Clifford, or their streetwise, one-eyed taxi driver will be able to protect the home front and save Wendy.
