Mother-of-two Rosemary is a woman under pressure. With two difficult teenaged children, a distant husband and a busy job, the stress is mounting. The loss of her internet connection pushes her over the edge. After waiting a month and two failed attempts to fix the problem, a third repair man arrives. When he too says he can't get her back online, his incompetence forces Rosemary to take drastic action. The repair man realises that Rosemary is not as naive as she first appears. She is a woman with a secret and is capable of causing him harm.
