When his mother (Dee Wallace) asks for help after his half-sister, Carolina, goes missing in Mexico, George (Tom Parker) travels to their home south of the border, where he teams with local Carmen (Ana Patricia Rojo), who's looking for a missing boy. They soon realize that legendary ghost J-ok'el -- a mother who drowned her own babies and now searches for children to replace them -- may be behind the disappearances in this Mexican horror flick.
