officier Rock (Koo), is a very careless officer. Many
times, his partner in crime, Rocky the K-9, has to help
out and save the day. During one crime scene, Rocky was in a
fight and injured itself. It couldn't be a police dog anymore
so Rock took it home as his own pet.
Leung (Hseun) is a pet lover. She feels that Rock is
a total irresponsible person when caring for pets. When her
first pet, Dong Dong was missing, she knew for sure it was Rock's
fault. When Leung found a stray named Dao Dao, it helped
her somewhat to forget her first pet. Later, when Dao Dao and
Rocky fell in love, the dogs had to suffer their owner's fighting
and headaches as well.
