From the liner notes

Melvin has dinner with some new friends. His loud and seemingly happy friend Joey is there, as well as two girls, Alex and Sarah. It's not clear who knows who or from where. They talk, delight each other with "tasty" stories, and accidentally tell each other what is actually going on in their lives as these sometimes crude and inappropriate stories bubble to the surface over dinner. A hilarious new film from the creator of "Mr. Show."
