Ming Lui devotes all her energy to her job as a customs superintendent. Ming's two capable subordinates, Lam Chi-kong and Moon Fung, always quarrel at work, but at the same time find each other attractive. However, their romance is short-lived, owing to their strong egos, and the two young customs inspectors soon fall in love with Kung Siu-yau and Lam Chi-kit respectively. Ming's newly developed relationship with rich publisher Tao Ling-shan faces challenges from Ling-shan's ex-girlfriend. Meanwhile, at work, Ming, Chi-kong, and Moon are forced to pay increasingly more attention to their careers as law enforcers.
