After facing the fact that they will be going to different colleges next year, best friends Seth (Jonah Hill) and Evan (Michael Cera) feel they must first complete the right-of-passage of going to a high school party and losing their virginity with the girls of their dreams. However, with their less-than-stellar track record in the ladies department, the two determine that they'll have to get the girls drunk to accomplish this feat. So they enlist their awkward friend Fogell to get a fake ID, which he obtains under the name McLovin. Will they get the booze to entice the girls and fulfill their plans, or will they arrive at college with dashed dreams? Either way, they have a night they will remember for the rest of their lives.
