DCS Foyle and Sgt. Milner investigate a series of strange events at a local manor house that has been converted to a hospital to treat RAF pilots suffering from extensive burns. Most of the incidents verge on the side of bad jokes, but when a more serious attempt is made on the life of an RAF Group Captain, they take a more serious interest. They learn that an RAF Sergeant with a criminal record, Gordon Drake, is living on a cottage on the estate and has a connection with the estate's owner, Sir Michael Waterford who may not appreciate the way the RAF has commandeered his home. Foyle also learns that Drake was having an affair with the wife of a doctor, Brian Wrenn, who also works at the burn hospital. Foyle's son Andrew, an RAF pilot, has also had several run-ins with Drake. Andrew is also suffering from fatigue and goes AWOL ending up at Sam's flat.
