Every year, the Doctor David Beck and his young wife, Elizabeth, meet at the same deserted lake to rediscover their love for each other, and inscribe one more year into 'their' tree. But that year was the last. Elizabeth was kidnapped and Beck knocked unconscious. By the time he woke up, his wife had been discovered dead, and horribly mutilated. For eight years he grieves.
