Jamie Lee Curtis continued her post-'Halloween' horror streak with this 1980 offering concerning the bloody avenging of the accidental death of a young girl six years later when those responsible are celebrating their prom. Several unrelated sequels followed.
A girl plummets to her death while fleeing from the taunts of four vicious classmates. Years pass: it is now prom night for the children who survived the incident, and someone -- or some thing -- is taking vengeance against them for their childhood sin. One by one, they drop.
