Seth and Evan are accepting the fact that they will be going to different colleges in the fall. Now, it seems more imporant than ever that they go to a high school party, and achieve some of their long time goals. This includes, but is not limited to, losing their virginity with the girl of their dreams by getting them wasted and being their "regret hookup." Their awkward friend Fogell gets a fake ID, with just the name McLovin, and agrees to get liquor to bring to Jules' a.k.a. Seth's dream girl's graduation party. All seems to be going well until McLovin is suckerpunched in the liquor store by a robber. When the police come, they try to get a story out of the clerk, but she is too worried about her exam tomorrow, so they question McLovin.
