March 1942: The US Army Corps of Engineers arrives in Hastings to build an aerodrome and Foyle needs to calm a local farmer whose land has been requisitioned by the government. Foyle also gets hooked into giving a lecture to the American GIs on local customs. It all takes a more serious turn when a local barmaid, Susan Davies, is found strangled. She had been seeing one of the GIs and was pregnant, but was also involved selling illegal whiskey for her employer, Alan Carter. Meanwhile Sgt. Milner investigates the death of friend, Will Grayson, who died in a house fire. He had been drinking at Carter's pub but wasn't drunk when he left and Milner can't quite figure out why his friend didn't get out of the burning house in time. Finally, Sam gets unhappy news from boyfriend Andrew.
