Better Living Through Chemistry
Doug Varney (Sam Rockwell), is unhappily married to Kara, (Michelle Monaghan). They have a son Ethan who is acting weird. Kara isn't interested in anything but staying fit and cycling; she teaches spin classes and wins the town's cycle race every year. Straitlaced Doug is bullied by his retired father-in-law, whose small-town Pharmacy he took over.
Elizabeth (Olivia Wilde), is a bored trophy wife, prescription drug abuser and one of Doug's best clients. She seduces the unhappy Doug and they begin an affair and do lots of pharmaceuticals. Doug's life is transformed by "better living through chemistry". Elizabeth persuades Doug to murder her husband Jack (Ray Liotta) so that they can run away together by tampering with the dosages of his heart medication. The plan fails when the delivery boy ODs on stolen pharmaceuticals. Doug realises that he can't abandon his son who needs him and straightens up. Elizabeth leaves Jack and heads overseas.
