The Alligator People

After being administered the drug sodium pentothal by two psychiatrists, amnesiac nurse Jane Marvin recalls a series of events from her repressed memories when she was known as Joyce Webster. In flashbacks, we see Joyce after marrying a young man named Paul Webster. Aboard their honeymoon train, Paul receives a telegram and leaves in a panic to make a phone call. When the train pulls out, Paul is missing, having vanished without a word. Throughout the following months, Joyce employs private detectives and searches for her husband. She eventually finds a lead: the address of the Cypresses Plantation that Paul entered on his college enrollment forms. Joyce travels to the desolate town of Bayou Landing, Louisiana. There, she meets Manon, a handyman at the Cypresses, and convinces him to drive her to the plantation.
