After graduation, Zhou Xiaodong (played by Du Jiang) went to Xingfu Community Hospital to work as a doctor. He is full of love, skilled in medicine, and handsome. He has always been the object of secret love and pursuit of many nurses! The community resident and beautiful nurse Liu Jing (played by Sun Yifei) is the most infatuated one. After a long period of silent attention, Liu Jing unexpectedly discovered that the prince charming Dr. Zhou has a quirk - he loves the puppy "Duoduo" with all his heart and almost perverted love! With "Duoduo" around, everything around him seems to have disappeared in Dr. Zhou's eyes, and he will not even look at Liu Jing. Liu Jing is jealous and helpless. However, it seems that a miracle has fallen from the sky. A "magic weapon" dropped from a window in the community smashed "Duoduo" to death. Dr. Zhou vowed to take revenge, and Liu Jing became a helper, having the opportunity to get closer to and understand Dr. Zhou more. During the investigation, "a community security guard who loves to eat dog whips, a foolish Erpang who has a one-sided love for Liu Jing, a weird uncle who walks his bird, a social big brother named Wuming, and a housewife Erpangma" have successively become "suspects". Dr. Zhou, who is crazy about dogs, has tossed out a series of funny and hilarious farces in the process of catching the real murderer. As the investigation deepens, Dr. Zhou finds that Duoduo's death seems to be more confusing and foggy, until his old classmate "Chopping Board Old Fart" shows up, and the big boss behind the scenes, the slingshot master Liu Jingma (played by Yuen Qiu), gradually surfaces, and Dr. Zhou's love for dogs has another hidden story... The truth is about to be revealed. When Liu Jing gradually gets the love, Dr. Zhou's first love girlfriend shows up with the halo of a headhunter in a foreign company hospital to win the love. How will the big boss use funny means to help his beloved daughter resist the enemy? (Source: Baidu Film and Television: http://www.bdvcd.com)
