Since his parents are leaving home for the weekend, Thomas is persuaded by his best friend Costa to hold a party at his house. Convinced that this evening could be the turning point in their lives, Costa spares no effort to spread the word. Soon, the first guests begin to appear, and the party dangerously takes off. More people continue to arrive, and more still, soon invading Thomas's backyard and house, as well as the surrounding streets and all the open spaces in the neighborhood. Incredulous, Thomas and his friends realize too late that they are the instigators of a movement that is impossible to control...
Another legacy from The Hangover and Superbad that goes bigger, even crazier. It is an epic party ever indeed!.
