Straight policeman Wu Minghan (Xu Guanghan) picked up a red envelope by mistake, but he didn't expect that the object in the red envelope was a man (Lin Bohong)! Minghan, who was forced into a ghost marriage, was unlucky all the way. Not only could he not get rid of the ghost marriage object, but he also messed up the drug case that policewoman Lin Ziqing (Wang Jing) had been laying for a long time. In order to save the crisis, Minghan, who is homophobic and afraid of ghosts, has no choice but to join hands with his ghost husband Maomao to cross the border to chase the murderer, even if they are different from humans and ghosts! An absurd journey with laughter and tears begins!
