Varios adolescentes son invitados a una vieja granja para pasar el fin de semana. Lo que no saben es que al caer la noche serán atacados por demonios sedientos de sangre.
Unos investigadores que experimentan con gatos detectan un extraño tumor que se desarrolla vertiginosamente en uno de los felinos. Cuando van operarlo para extirpárselo, el gato logra escapar dejando un rastro de sangre y muerte tras de sí. En su huida sube a bordo de un yate privado que está a punto de partir hacia el Caribe y que será por unos días el lugar de recreo de un grupo de jóvenes.
