Gavin, a new pupil at school who has some history with Jock, ignites a jealousy in Conor that brings a tense situation to comical heights.

Conor, Jock and Mairéad, always tight on cash, come up with a hare-brained idea to become business owners as they buy a second hand chip van to try make extra money.

A day trip in memory of Conor’s dad and the appearance some mysterious cash cause confusion, with the interference of Billy Murphy creating a perfect storm of mayhem.

Billy Murphy enlists the help of Conor, Jock, and eventually Mairéad, to avoid getting killed by a former cellmate of his who has just been released from prison.

With a new arrival on the way, Jock is getting anxious and Principal Walsh isn’t helping. But a challenge to Jock brings about surprising results.

The baby is due and everyone is frustrated with the nonstop arguing of both families, so an ill-advised weekend break for all is organised.
