When a dead body is found on Hastings beach the main suspects are an American multi-millionaire, an old flame of Sam's and a man that claims to be a Ditch refugee. Sam looks for a place to live when her house is destroyed by a bombing raid.

Foyle suspects an illegal fuel racket when a truck carrying barrels of petrol crashes. Sam convinces Foyle to let he go undercover at the fuel depot, but what she learns may be very bad for Foyle's son Andrew.

It is October 1940 and a young secretary plummets to her passing at the London headquarters of a multinational company. A member of the Home Guard ishuged in Hasting and Foyle and the minister think the passings are linked.

Foyle is suspended from duty for spreading malicious rumors. During the time Foyle attempts to clear his name his replacement sends Sam back to the transport corps.
