Uninvited
When three estranged sisters, Kimmy Granger, Ivy Lebelle and Ashley Lane, reunite at their stepmother Nancy's funeral, they are introduced to Ella Hughes and Danny D., a mysterious duo who claim to be Nancy's shunned biological family. While Nancy never mentioned any other family to the three siblings, they have no reason no to believe Ella and Danny -- while they may be a little strange, they don't seem particularly sinister -- at first, anyway. Danny and Ella quickly work their way into the lives of the three sisters, using sex to turn them against one another in an attempt to get their hands on the family fortune.
