Miguel Avila, a gifted choreographer, runs a dance school with his partner Kate. Unlike her, he's meanly thrown from the TV show Dance Tonight by producer Quinn. Fellow star Teresa is murdered, in a way that may fit Kate's twin's earlier murder, but also frees her spot for rivals. Studio security agent Tony spares no effort to make up for the police's failure to make any progress, as creepy incidents keep happening, suggesting a mad fan is stalking Kate, whom Miguel now wants to quit the show, kidnapping their dog, arranging for an intruder and planting a venomous spider.
