It's the school holidays and Sam and his best friend can't wait to see Cry Wolfe, the first movie starring their favourite crime-fighting hero.

But Sam's mum has set him a challenge. He can only go and see the movie IF, and only if, he can make it through the entire holiday without telling a single fib.    

Can Sam go six whole weeks, without a single porky!? 

WARNING: contains fibs, farts and zumba-dancing mums.
