advertisement from 1960 for Tormented and co-feature, Caltiki – The Immortal Monster.]] Jazz pianist Tom Stewart lives in a Cape Cod island community and is preparing to marry his fiancée, Meg Hubbard. Shortly before the wedding, Tom's ex-girlfriend Vi Mason visits and informs him that she will end his relationship with Meg, using blackmail if necessary. While they argue atop a lighthouse, the railing gives way, and Vi falls. She manages to hang on briefly while she cries for help, but Tom refuses and watches her fall to her death.
The next day, Tom sees Vi's body floating in the water. After he retrieves her, the body dissolves into seaweed. Tom tries to forget, but over the next few days, Vi's watch washes up on the beach, strange footprints appear in the sand, Vi's ghost appears and tells Tom that she will haunt him for the rest of his life, and when Meg's little sister Sandy asks to try on the wedding ring, a disembodied hand makes off with it.
During a pre-wedding party, Vi's disembodied head appears in a photo a guest takes of the couple. Later, Vi taunts that she will use her voice to tell the world how Tom killed her. To add to his dilemma, Nick Lewis, a beatnik ferryman, comes to claim the $5 Vi owes for her passage to the island. Tom's haste to pay causes shifty Nick to stick around, and his attempts at blackmail lead to his death, which Sandy inadvertently witnesses, unknown to Tom.
Sandy, who idolizes Tom, remains silent, although she almost speaks up at the wedding when the minister asks if anyone has any objection. Before she can speak, the church's doors burst open and cause the flowers to wilt and the candle flames to be extinguished, bringing the ceremony to an abrupt, unpleasant halt.
That night, Tom returns to the lighthouse and tells Vi that he is leaving the island. When he finds Sandy eavesdropping, he realizes that he is trapped: Sandy knows too much and could tell Meg and the community. In desperation, he leads Sandy up to the broken railing with the intent to push her over. However, Vi's ghost swoops down on him, causing him to go over the edge as Sandy watches.
The islanders find Vi's body, and Tom's soon afterwards. When his body is placed next to hers, her arm somehow manages to land across him. On Vi's hand is the wedding ring, signaling that Tom is now forever with Vi.
