Plot

Eva Blue gets high on marijuana in her living room, and falls asleep on the couch. A woman named Elise is then shown in bed with her husband, Nick, who she tries to talk into having sex with her. Nick ignores his wife's advances (not for the first time) and berates her appearance, housekeeping, and cooking before heading to a business appointment, mentioning on his way out that they have been invited to dinner at Eva Blue's house. Elise calls her lover over, and Nick buys a meat cleaver at a hardware store.
