Boy from the Hills' parents are going away a week before Christmas, so in true Crongton style, McKay and the rest of his friends persuade him to throw a house party. But, Boy from the Hills must keep his dad's precious Aston Martin safe, as well as look after his neighbour's dog until Boxing Day.
Just before the party, Boy from the Hills runs into school bullies, Vincent Chapman and Donald Thompson, and when they find out about the party, they do everything they can to get in.
House party hijinks, romantic entanglements and dance competitions abound in this light-hearted instalment of the beloved Crongton series.
