Liam's mom, Jean, is in prison but is due to be released in time for his 16th birthday. This time Liam is determined that things will be different. He dreams of a family life he's never had, which means creating a safe haven beyond the reach of wasters like Jean's boyfriend Stan and his own mean-spirited grandfather. But first he's got to raise the cash - no mean feat for a skinny teenager. It's not long before Liam and his pals' crazy schemes lead them into all sorts of trouble. Finding himself dangerously out of his depth, Liam knows he should walk away. Only this time, he just can't let go.
