Erin McKenna, a beautiful songwriter married to a crooked LA County sheriff's deputy, is kidnapped by the ruthless leader of the powerful Gulf Cartel. But his demands turn out to be as unusual as the crumbling castle in which Erin is kept. Under threat of death, Armenta orders Erin to tell his life story - in music. As the mesmerizing music and lyrics of Erin's song cascade from the jungle hideout, they serve as a siren song to the two men who love Erin: her outlaw husband, Bradley Smith, and the lawman Charlie Hood - two men who together have the power to rescue her.
