Martin Moone is 11 and completely fed up with being the only boy in a family of girls. He's desperate for a decent wingman to help him navigate his idiotic life. So when best mate Padraic suggests Martin get an imaginary friend - or IF for short - he decides to give it a go. His first attempt is Loopy Lou, a hyperactive goofball who loves writing rubbish rap songs. But Martin soon gets fed up with Lou and decides to trade in his IF for someone a little less wacky.
