On a fog-shrouded island, jazz pianist Tom Stewart is preparing to marry his wealthy fiancée Meg Hubbard, despite having recently ended an affair with a woman named Vi Mason. Days before the wedding, Vi appears, threatening to expose their past relationship to Meg, thus ruining Tom's prospects. In a moment of panic on the island's lighthouse, Tom watches Vi accidentally fall to her death. In a state of shock and fear of losing everything, he chooses not to report the incident, hoping to leave the affair and Vi's death behind as he moves forward with his life.

However, Tom's decision soon leads to unforeseen consequences. He begins to be haunted by mysterious occurrences and apparitions, suggesting that Vi's spirit is not at rest. The hauntings start to take a toll on Tom's nerves and his relationship with Meg, as he becomes increasingly isolated by his guilt and the secret he desperately tries to keep hidden. The presence seems intent on making Tom pay for his actions, interweaving his fate with remorse and fear, setting the stage for a haunting tale of love, betrayal, and supernatural retribution that threatens to destroy him.
