Operation Nativity

When Oscar and Molly rush outside to investigate a crash in the night, they're not expecting to find a dazed Angel Gabriel wandering around their grandparents' back garden. And they're certainly not expecting to find themselves in a race to save Christmas.

But if they don't track down a missing shepherd, wise man, donkey and the actual Mary and Joseph, who've all crash-landed in Chipping Bottom, not only will Christmas cease to exist, but they will too.

Operation Nativity is on.
