In Sam Prim’s “Mary’s Mixtape,” a stolen cassette tape triggers a lethal obsession. After pocketing an abandoned Walkman, Mary becomes entranced by a euphoric melody that masks a violent, supernatural compulsion. The music acts as a destructive siren song, pushing Mary toward self-harm and endangering her sister. As she explores the tape’s B-side, the dark fate of the previous owner is revealed through chilling recordings. This 80s-inspired slasher short serves as a metaphor for addictive habits and the terror of temptation. Even when the horrifying cost is clear, Mary finds she cannot escape the tape’s haunting call.
