Blackjack (1997)

Through a mysterious method, night club owner Se-geun (Choi) has come into possession of a large sum of money. Having this money has done nothing for his character as he is self-centered and selfish. Entering his solitary life is Eun-young (Kang). Married to a very common man, Eun-young longs for freedom and wealth. She seduces him and at a carefully chosen time plays her card "I want you to kill my husband..." With that deadly request, the game begins.
