When young Elliot gets a labourer's job at Mr Evans's after being sacked from a pig farm for liberating six of its sows, he thinks he'll have even more opportunities to lean on gates or stare at fields. But his best mate Spike keeps getting him into trouble, first by showing him what is being grown in a tucked-away polytunnel, and then turning up at his caravan's door with a van full of weed. As Elliot tries to help his friend get rid of the hot merchandise, they find themselves at the receiving end of a cruel cat-and-mouse game.
