Revenge

Jennifer (dubbed "Jen") is an American socialite who is in a secret relationship with her married neighbor Richard. The two fly out to Richard's secluded home in the middle of the desert for a weekend together before his annual hunting trip with friends Stan and Dimitri; Richard's helicopter pilot gives him some peyote as a gift before he departs. However, Stan and Dimitri arrive a day early, disappointing Richard, who was hoping to keep Jen a secret. While the three men and Jen have a fun night of drinking and dancing, Richad tells Jen to hide the peyote from Stan and Dmitri; she hides the peyote in her necklace.
