Only worth watching if you appreciate some eye candy in the shape of young and attractive Alain Delon and Senta Berger.
The plot is about amnesiac George who after a terrible car crash from which he recovered without any bruise or visible sign, apart from a sprained ankle, is sent home to recover.
'Home' is a mighty isolated mansion where George lives with wifey Christiane and shady Chinese servant Kim. George and Christiane are just back from Hong Kong, where they made a ton of money and their only visitor is their 'friend' Freddie.
By now you'll know that this is a relatively cheap production, employing only 4 actors (albeit a couple of big names) and a few extras for a few scenes and taking place almost exclusively in the creepy mansion.
Delon is an unconvincing George. While thinking his real name may be Pierre Lagrange, George's only purpose seems to be getting into Christiane's pants. Talk about the French being obsessed with sex... It takes a while for dumb George to realize that the 'medicine' wifey and pal force down his throat might not be so curative after all.
Given the setting, one can see the denouement coming a long time away, the only question mark being if Christiane will make it, while 'George" undoubtedly should.
