The Alligator People is a 1959 American CinemaScope science-fiction horror film directed by Roy Del Ruth.

[6][2] 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.

Aboard their honeymoon train, Paul receives a telegram and leaves in a panic to make a phone call.

She eventually finds a lead: the address of the Cypresses Plantation that Paul entered on his college enrollment forms.

However, after learning that Joyce has missed the last train back to town, Lavinia reluctantly invites her to stay the night under the proviso that she must not leave her room.

Back at the house, the maid Lou Ann is caring for Joyce while Paul presses Mark to give him an untested cobalt treatment in hopes of curing his condition.

The next morning, Mark summons Joyce to his lab and tells her about his experiments with reptilian hormones that are capable of regenerating limbs.

After Paul received the telegram notifying him of this, he hurriedly left the train and came home in hopes of reversing his condition.

The machine starts shooting powerful rays at Paul that transform him into a bipedal, reptilian monster with an alligator-like head.

Scrambling away from his wife, Paul stumbles into quicksand and slowly sinks out of sight, seemingly meeting his demise.

Concluding that her amnesia has allowed her to suppress the horror and resume a normal life, they decide not to tell her about her past.
