While on her way to a weekend with her mother, Purdey is kidnapped. Steed receives a ransom phone call which makes various demands, first of money and then secret papers on the full allied attack. Meanwhile, Steed's fellow agents become suspicious, and when one of them is found dead, shot by Steed's gun, Gambit is ordered to bring Steed in. Steed overpowers Gambit and heads off to the rendezvous point agreed with the kidnappers, a disused funfair. Steed attempts to rescue Purdey, but the two of them are held down by enemy fire. Gambit arrives in one of the Ghost Train carriages, and together the three of them overwhelm the kidnappers, leaving the toughest one just for Purdey.
