Ring of Terror

Plot: Med student Lewis Moffitt harbours a secret fear of the dark stemming from a traumatic childhood incident involving a corpse. Nonetheless, he pretends to be unaffected during the first autopsy witnessed by his class, and generally affects an attitude of fearlessness. This, however, inspires his would-be frat brothers to conceive a particularly morbid initiation ritual -- one which will, inevitably, go horribly awry. (Source: IMDB)
