Nursery school teacher Jenny Greengrass and her boyfriend Steve Taylor journey to a remote lake in the wooded English countryside. Hiking to the lakeside, they meet Adam, a young boy gathering insects. Relaxing beside the lake, the setting is disrupted by a group of delinquent teenagers, who have ridden their bicycles to a spot within a few metres of the young couple. After they sleep overnight in their tent, they find food supplies infested with insects and their car tire damaged by a bottle left behind by the teens.
