Rhona wants a night out with the girls and Paddy wants a night out with the guys but someone needs to watch the baby. Paddy and Marlon decide on a big night in but wake in the morning wondering what happened the night before.

The Dingle family are feeling the pinch, resorting to eating scraps and selling old bric-a-brac to make ends meet. Clutching at straws, Zak sets off with Belle to buy a Eurobillions rollover week ticket. As Zak and Belle make their way to purchase the ticket, we enter two parallel universes and the fun enfolds as fate serves up very different futures with their lucky numbers and potential winning ticket…. We then seamlessly experience the two ever shifting worlds as the most turn of events leads the extended Dingle family into two parallel but polar opposite futures. Will it be the reality of winning the lottery that brings delight, or will the harsher reality of lies and bogus tickets leave the clan counting the cost of nearly winning a fortune? The havoc unfolds with hilarious results as the film asks the question ‘How much would winning the lottery change you?’
