A nerdish British bank clerk named Freddy Clegg (Terence Stamp), a neurotic recluse whose only pleasure is butterfly collecting... Clegg wins $200,000 in the British Football Pool. He purchases a huge country estate, fixes up its cellar with all the comforts of home, then kidnaps Miranda (Samantha Eggar), an art student whom he has worshipped from afar. The demented Clegg doesn't want ransom, nor does he want to rape the girl: he simply wants to collect her... (allmovie.com)
