Sam and Ilsa have spent most of their high school years throwing parties for their friends and now they've prepared their final blowout, just before graduation.

With Sam and Ilsa, the sibling revelry is always tempered with a large dose of sibling rivalry, and tonight is no exception. 12+ One night. One apartment. Eight people. What could possibly go wrong?
