story
Nick Hendricks (Jason Bateman), Dale Arbus (Charlie Day), and Kurt Buckman (Jason Sudeikis) are friends who despise their bosses. Nick works at a financial firm for Dave Harken (Kevin Spacey), who abuses Nick constantly. Nick puts up with it in hopes of a promotion, but Harken instead gives the job to himself. Dale is a dental assistant to Dr. Julia Harris (Jennifer Aniston), who wants to have sex with Dale, who is engaged to Stacy (Lindsay Sloane). Julia constantly sexually harasses Dale, even forcing him to look at her while she wears only a lab coat, panties, high heels and thigh high nylon stockings in the office. Kurt enjoys his job working at an industrial company for Jack Pellitt (Donald Sutherland), who treats Kurt like a son, but Jack dies of a heart attack one day, leaving his cocaine-addicted biological son Bobby (Colin Farrell) in charge. Bobby threatens to run the company into the ground by having the overweight, whom Kurt believes is pregnant, and handicapped employees fired along with doing cocaine and having prostitutes in his office.
One night over drinks, Kurt suggests their lives would be happier if their bosses weren't alive, but Dale says it's a silly idea to kill their bosses. However, the next day, Julia invites Stacy for a free dental checkup and while she is unconscious, Julia threatens to show Stacy photos of what looks like Dale having sex with Julia, taken while he was unconscious. That night, Dale finally agrees to help kill their bosses and Nick reluctantly does the same. They go into a bar and meet Dean "Motherfucker" Jones (Jamie Foxx), a paroled ex-con who will only agree to be a murder consultant. Jones suggests that the three stage murders that look like accidents and that they do each others' bosses so as to not be traced.
The three first do reconnaissance at Pellitt's house. Kurt goes into his bathroom and rubs Pellitt's toiletries on his butt before taking his cell phone off the nightstand. Nick and Dale find his cocaine stash in the living room but accidentally spill it on the carpet. The three then go to Harken's house where Dale waits in the car with a peanut butter sandwich. Dale then throws his sandwich bag out the window where Harken, returning from a jog, picks it up and berates Dale for littering. Harken then suffers an attack due to his peanut allergy, but Dale manages to revive him. Nick and Kurt, watching through the window, think Dale is stabbing Harken to death and flee the house, with Kurt accidentally dropping Pellitt's phone under the bed. Dale catches up with Nick and Kurt and tells them what happened. Nick and Kurt decide they can use Harken's peanut allergy to poison him while he's taking a shower and also spike Pellitt's cocaine with rat poison.
