Jazz pianist Tom Stewart (Carlson), who lives in a Cape Cod island community, is preparing to marry his fiancée Meg Hubbard (Lugene Sanders). Shortly before the wedding, Tom's old girlfriend Vi Mason (Juli Reding) visits and informs him that she will end his relationship with Meg, using blackmail if necessary. While she's arguing with him atop a lighthouse, the railing she's leaning on gives way. She manages to hang on briefly, but Tom refuses to help and watches her fall to her death.
