It is about a pretty girl luring a luckless gambler into a dangerous poker game in a nutshell.
The Main Story
Barney Lincoln ( Warren Beaty ) is a wealthy American playboy who meets an attractive dress designer in London called Angel McGinnis ( Susannah York ). However, he only has one memorable date with her before he leaves for Geneva.
Once he gets to Geneva, he breaks into the Kaleidoscope card factory, which was the factory that made all of the playing cards for the casinos in Europe.
His reason for breaking in was to etch secret marks on the printing plates so that he could make money at the casinos using these cards.
He then goes to Monte Carlo, where he is reunited with Angel, and makes a fortune gambling using the marks on the cards. He also went to other European casinos and continued to win more money until he returns to London with Angel.
The Ending
He soon finds out that whilst he was in Monte Carlo with Angel, she became suspicious of his winnings and tells her Father Manny, a Scotland Yard Detective.
Manny then tells Barney that if he doesn’t want to be arrested, he must help him capture Harry Dominion, a drug smuggler who liked playing poker.
Accompanied by Angel, Barney sits in on a game with Dominion and wins every single hand. He even one a hand played with an unmarked deck. Dominion was not happy about losing, so he uses Angel as bait to lure Barney to his country estate where he beats him up and takes back his money.
Barney and Angel try to escape but are chased by Dominion’s henchmen. The movie ends when Manny and his detectives from Scotland Yard arrive to rescue Barney and Angel.
