MR. KO, who is hot on bowling, has recently bought a bowling center. He invites his staff and their family to play at the center but everybody leaves early with an excuse. MR. KO is unhappy about this. In TUNG’s opinion, he should try to raise his staff’s interest in bowling. Ko Tsim Daily is organizing a bowling competition. Everybody is coveting the attractive prizes. KWAI teams up with MEI-CHING, CHING and SUSAN. They invite YEE to be a backup, but she hates the game. MEI-CHING twists her hands as she is moving YEE’s old notes. So YEE has to play for her. YEE is surprised to discover that none of her teammates knows the proper posture. So she shows them the correct way of playing the game and plays a strike. Impressed, KWAI and the other girls try all they might to talk her into taking part in the game.
