Spring has sprung in quaint Taylorsford, Virginia, and the mayor has revived the town's long-defunct May Day celebration to boost tourism. As part of the festivities, library director Amy Webber is helping to organize a research project and presentation by a local folklore expert. Spring takes on a sudden chill when a university student inexplicably vanishes during a bonfire, and Amy's neighbor Richard Muir becomes a person of interest. The student is found in the mountains, with no memory of recent events -- and a body nearby.
