Sam and Ilsa Kehlmann have spent most of their high school years throwing dinner parties, and now they’ve prepared their final blowout, just before graduation. The rules for the twins are simple: they each get to invite three guests, and the other twin doesn’t know who’s coming until the guests show up at the door. With Sam and Ilsa, the sibling revelry is always tempered with a large dose of sibling rivalry, and tonight is no exception. One night. One apartment. Eight people. What could possibly go wrong? Oh, we all know the answer is plenty. But plenty also goes right – in rather surprising ways.
