Paul gives Rachel a family voucher for a theme park which is valid for six months. Just before it reaches its expiry date - and with a neighbour's dog in tow - the Jessops finally attempt to use it.

When Rachel receives a family pass to Jungle World adventure park as a birthday present from Paul, to be redeemed anytime in the next six months, the family start excitedly planning their big day out.

However, as work and home pressures heighten over the course of the year, the Jessops only remember to use Rachel's voucher on the final day that it's valid. Racing against the clock to get to the park before it closes, with an uncooperative dog that Sue is looking after for a neighbour in tow, will the Jessops snatch victory from the jaws of defeat and give Rachel the birthday day out she so badly needs?
