An old policeman, who was about to retire and was timid everywhere, found that he was terminally ill during the medical examination (in fact, he had been replaced with a card for the sample). In order to earn an education grant for his son who is still in primary school, he must be killed in the line of duty in the short time left. As a result, he began to carry out the task crazily, but God happened to be against him and always let him finish the task unharmed.
