Read the complete plot breakdown of The Severed Arm (1973), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

Jeff Ashton is at home when a mail carrier delivers a strange package. Upon opening the wrapped item, he is horrified to see it contains a severed human arm. He immediately contacts his friend, Doctor Ray Sanders, and the two discuss an incident five years before when, as part of a group of cave explorers, they were trapped by a cave-in. In order to avoid starvation, the group had cut off the arm of one of their fellow cavers, a man named Ted Rogers, planning to eat it. However, moments after doing so, the entire group was rescued and they quickly concocted a cover story for the authorities, saying that Ted had lost his arm in the cave-in and concealing that they had cut it off with a knife.

Jeff and Ray try to find Mark Richards, who is now a police detective. Mark finds Teddy Rogers, Ted’s daughter (named after her father), but she initially refuses to help the group find her father who has now apparently disappeared. However, after Jeff’s friend Mad Man Herman, another one of the cavers who is now a radio personality, is brutally killed on air during his radio show by having his arm hacked off, Teddy agrees to help the group find her father.

The killings continue until only Jeff and Mark remain. They attempt to trap the killer, who they believe is Ted, but Mark has his arm ripped off after being pushed from a cliff with a rope around his wrist. Jeff is then knocked unconscious by the killer after a struggle. When Jeff awakens, he is in a bare white room and it is revealed that Ted’s daughter Teddy was behind the killings. Her plan was for her brother Roger, masquerading as their father (who is now in fact catatonic) to kill Jeff’s friends and then kidnap Jeff, as the original leader of the caving group and who came up with the idea to cut off her father’s arm. Jeff is then sealed in a room to starve, with the only way to avoid death being for Jeff to cut off his own arm and eat it. The film ends with Jeff, imprisoned alone, shouting “Never!”
