How to evaluate the film "Three Missing Ones"?

In the film, every couple will be entangled with each other. The police want to catch all the gangsters, the doctor is between the gangsters and the police, and the three people are implicated in each other. If gangsters want to contact their companions, the police will naturally stop them. So the bandits used the doctor's psychology of wanting him to do surgery to save lives to stimulate her, and the doctor was really persuaded to dial him. Before, the bandit had been very gentle, and the last sentence "kill him" on the phone immediately became cruel and resolute.
