Tak Wah (Andy Lau) likes playing cards. He makes a living by playing cards and is famous for his good card skills and good card character. Wing Kei (Gigi Leung), who has been in love with him for many years, has never been able to marry Tak Wah because of his poor card character, which makes her feel disappointed. Tak Wah's younger brother Tin Lok (Louis Koo) knows that his brother has to make a living by playing cards to support his mother who suffers from dementia and himself who is studying, so he decides to compete in cards with Ching Wan (Lau Ching Wan), but he loses repeatedly. In a card game, Wing Kei is unwilling to be repeatedly rejected by Tak Wah because of the problem of card character, so she curses him to "play bad cards for the rest of his life" and leaves with Ching Wan, who also failed to become his apprentice. The curse really worked, causing Tak Wah's family to fall into poverty, but he is always optimistic and believes that his "good friend" will come back. In the mahjong competition held by his brother's company, he played steadily all the way and faced Ching Wan again. Can he win in the end?
