Clothing store owner Wang Juan died on her doorstep.
The Criminal Investigation Detachment sent two police officers to investigate.
One is young Liu Chen, whose resignation application only lacks the signature of the director.
One is Uncle Yao, a veteran policeman who will retire next month.
One is weak and the other is old.
Wang Juan's father and brother didn't care at all who killed Wang Juan.
They only care about when they can get Wang Juan's shop, house, and deposit!
Intention: I can resign and you can retire, but before that, stand on the last duty.
