 Terrified of holding the  worst-ever party , the over-honest and over-obsessive Lance faces his fear when his parents go away for a dirty weekend. He and porn-addicted best mate Henry plan the party, the only problem being that they are each planning different parties. When Steph, Lance s perfect woman, turns up with the man-eating Abby and the man-hating Heather (plus some unexpected gatecrashers) and when Henry s plan kicks in, Lance sees his dreams painfully fall apart as the worst-ever party gets progressively worse. But is there light at the end of a very dark tunnel?
