90 Minutes is a Korean movie about a selfish man who is drunk on becoming successful. He will do whatever it takes.
He is a film director who constantly has success on his mind. Not in a good way, but in a way that can be dangerous to others. He wants wealth and fame, not true happiness. He marries a girl who comes from a very wealthy family. Her father is a power CEO and through the marriage, he is anxious at the thought of inheriting all of his wealth.
However, things get ugly when a girl that he had a one-night stand with reappears in his life and threatens him that she will reveal the video. If the wife were to see the video and know about his affair, everything would be over. The money, and positioning that he had attained so far would go down the drain.
