The TARDIS arrives in 1925 England where the Doctor ends up playing in a local cricket match due to a case of mistaken identity. The travellers accept an invitation to a masked fancy dress ball, but events take on a more sinister tone as murders are perpetrated at the country home of their host, Lord Charles Cranleigh.
