Matthew Malarkey has hit the big four-O.

To celebrate, he plans nothing more than a quiet dinner for two with the lady in his life. But his friend Cecil Delaney has other ideas. In Cecil’s eyes big birthdays mean big parties and there’s no better place to party than Las Vegas, Nevada. In the spirit of keeping the dream alive, Cecil organises a surprise trip to the bright lights of Sin City. With his plans hijacked, Matthew decides to play it low key. But it’s hard to stay low key in Vegas and when Matthew inadvertently gets mixed up with the wrong people, he finds himself gambling with a much higher stake than he had anticipated - his life!
