It's a roasting hot summer day and two lads are messing about on the roof of their building. Chatting about their favourite football teams, teasing and kicking a ball about until they espy a balding gent several floors below on the pavement. Out come the eggs. It turns out that they are quite good shots, indeed you can also ask a policeman who rather recklessly steps from the safety of his car shortly afterwards. Then one of them takes to his bike, and... Well suffice to say this is an entirely unexpected and darkly comedic ending to an otherwise simple and mischievous enterprise with two engagingly natural performances from Adrián Gordillo and Adam Jezierski showing us two boys at play in the sun. It's actually quite hard to describe but if you've a spare ten minutes then give it a go. There is a lot of Castilian dialogue but you don't need to be conversant with that to get the gist, and to enjoy - if that's the right word - their altitude antics.
