The film is set in 1988 Los Angeles. Matt Franklin (Topher Grace) is a recent MIT graduate who works at a Suncoast Video store while trying to figure out what he wants to do with his life, something that his police officer father (Michael Biehn) has grown impatient with. While working one day, Matt's high school crush, Tori Frederking (Teresa Palmer), randomly walks into the store. After pretending that he doesn't work there and saying that he works at Goldman Sachs in an effort to impress her, Tori invites Matt to a Labor Day party, hosted by Matt's twin sister Wendy's (Anna Faris) boyfriend, Kyle Masterson (Chris Pratt), at his hillside home.Later that night, Matt, Wendy, and Matt's best friend, Barry Nathan (Dan Fogler), head to the party. On the drive over, Barry steals a brand new Mercedes-Benz convertible from the car dealership he got fired from earlier that day, justifying his actions by saying that Matt needs the convertible if he really wants to impress Tori. The trio arrive at the party. While there, Matt catches up with an old classmate (who actually works at Goldman Sachs) and then awkwardly tries to woo Tori. Barry snorts some cocaine he found in the glove box of the stolen convertible and gets involved in a dance-off, and Wendy's boyfriend proposes to her in front of everyone at the party. She says yes, upsetting Matt, who doesn't think that Kyle will support her in her dream to attend graduate school at the University of Cambridge. Tori eventually invites Matt and Barry to another party her boss is hosting in Beverly Hills. Matt takes Tori there in the Mercedes, while Barry rides with her two friends in another car, using the cocaine as an enticement to let him go along. Barry has a wild sexual encounter with an older woman while Matt and Tori continue to mingle with each other, after Matt's successful 'put down' of Tori's boss, a habitual sexual harasser. They leave the party to go into a neighbor's backyard where they jump on a trampoline, play truth or dare, and end up having sex.Meanwhile, Wendy shares her unopened admissions letter from Cambridge with Kyle, and it is revealed that she was not accepted. Kyle is visibly relieved, while Wendy is visibly upset. Matt confesses to Tori that he doesn't actually work at Goldman Sachs. Tori gets extremely upset at his deception and storms off, back to her boss's party, leaving Matt guilt-ridden. Matt finds Barry there and they leave the party, and Matt tells Barry about how he told Tori the truth about his job. Barry patronizes him for not trying to have just one night of enjoyment and attempts to lighten the mood by offering Matt a line of cocaine, despite him driving. Matt, feeling vulnerable, attempts to snort the cocaine, but ends up driving the convertible off the road and into a ditch. A police cruiser soon arrives, and it turns out to be Matt's dad and his police partner. Already disappointed with Matt's unwillingness to choose a career path, Mr. Franklin damages the convertible even more as a means of coercing Matt to get a better job in order to pay off the damages. He takes Matt and Barry into custody, but lets them off in the neighborhood with a warning. Matt apologizes to his dad for being such a failure, to which his dad replies that because he's never even tried to succeed, he's actually less than a failure. Then, in a less condescending tone, he encourages Matt to take a shot at anything in life.Knowing Tori has left her car at the party, Matt and Barry make their way back there, where bets are being placed on who will "ride the ball", a giant, steel sphere that someone enters and rides as it's rolled down a hill (something Matt's dad has stated that nobody has done since he himself was a kid). Matt finds Tori at the party and tries to apologize, but Tori is unwilling to forgive him. Feeling he has nothing to lose, Matt volunteers to "ride the ball". When he does the ball rolls downhill uncontrollably, hitting several parked cars and eventually flying off an embankment before landing in a backyard swimming pool. Matt almost drowns as the ball sinks, but manages to escape just in time. Barry rushes to the scene and walks with Matt back toward the party, meeting up with Wendy and Tori, who are elated to discover he wasn't killed. Matt apologies to Tori, and she forgives him after playing a little hard-to-get and then gives him her phone number. All four return to the party, which is beginning to wind down as dawn approaches. All who are still there 'whoop' it up at Matt's successful return.Wendy, after realizing Matt was right all along, ends the engagement and breaks up with Kyle, who experiences a crying breakdown. Pondering his future with a Goth-type girl he met at the party, Barry is told by her that maybe he should go to college. Outside, as she leaves the party, Matt boldly kisses Tori goodbye. Matt's dad is shown investigating the scene where the steel ball was found. He finds Matt's Suncoast Video name tag floating in the pool, and smirks proudly. Barry staggers out of the party house, now in a shambles, to meet up with Wendy and Matt, who asks "Who wants breakfast?", and the three leave together as the sun is rising.
