A rich woman TSEUNG TIN NGOR (Shiu Mei Ki, Maggie)’s beloved dog CANDY has got behaviour problems since NGOR is being kidnapped. After released, NGOR takes CANDY for various medical treatments but none of them is helpful to cure its illness. Desperate NGOR finally finds LAI TSUN SING (Cheng Jut Si), a retired police canine officer, who has just opened a kennel in the walled village. NGOR asks SING to give CANDY training but it creates discord between both of them. When CANDY’s condition is getting better and better, NGOR is pleased and shows deference toward SING. NGOR feels obscured of the kidnapping and she misconceives that the landlord of the kennel, CHOW YUNG KUNG (Ma Steven), is one of the kidnappers. SING gets his trained dog BINGO carrying out an investigation. They finally prove that KUNG is innocent. KUNG appreciates Sing’s efforts and he starts joining the course for learning how to be a dog lover. LAI SIN YUE (Chung Linda), SING’s veterinarian daughter, is aware of her feeling towards him since then.
