It's May Day and the town waits excitedly for this year's pagan parade to begin. Local teenager and dark horse, Linus Newcombe, watches woefully as the love of his life, Caitlin Sutton, snogs a rival. Meanwhile, on the other side of town, Caitlin's twin and the beautiful young May Queen Hattie Sutton, catches Linus's dad Everett's eye as she passes him on her bicycle. As Hattie travels her fateful journey to appear as the town's symbol of new life, she passes various other residents, too - One is Fiona Hill and ex-copper, now housewife, who struggles to get her three kids down to the festivities, while her husband, PC Alan Hill, oversees proceedings at the parade. Meanwhile, wealthy community figure and property developer, Malcolm, smokes a cigarette, waiting for his nagging wife Gail to leave the house, is that malice in his eyes as Hattie cycles past? Wannabe local hero Steve Docker makes himself useful with traffic signs, while his more spiritual brother Seth dances a jig disguised as a 'Green Man'. Little do most of these people know that they will be the last people to have seen Hattie alive. One of them is her killer.
