Mayday is a gripping new crime-story set against the picture-perfect backdrop of a traditional town, one that is thrown into a sinister and paranoid world as its community discover the gruesome murder of a young girl. When the towns community comes together to celebrate Mayday, the yearly pagan public holiday, the horrific murder will unfold through the eyes of four characters. Each who suspect that the murder of the young-girl was by someone they know and trust; but they must keep silent. Mayday is an original drama from the BAFTA-winning producers of Spooks and The Hour.
