Arabella Stewart and her best friend, Ida Byington, look forward to a long weekend with college girlfriends on a remote Lake Erie island. Bootlegged booze and hidden grievances soon shatter the peace. When a gale knocks out electricity and telephone service, the women become stranded. After one dies, Bella's suspicions increase. Who is responsible?

Jax Hastings, now a Prohibition agent, returns home to see Bella, only to find her away. When he and Griff Biggins, Ida's beau, try to reach the women by telephone, they learn about the death--but not who died. Alarmed, they head to the island, where Bella and Ida reveal their suspicions--about rumrunners on the island and the suspicious death of their friend. Soon, clues point to several people who may be at the heart of a fatal reunion.
