Richie and Potsie plan to host a poker night at the Cunningham house as Howard and Marion will be out of town. However, their plans change when three young women stop by after their car breaks down, and Potsie invites them to stay the night.

With his parents out for the evening, home-alone Richie recovers from the Asiatic flu, waits for his friends to sneak him pizza and a movie, and surprises a burglar in the living room.
