Ma Liu has a happy family, but a paternity test leads him to learn that his son may not be "his own", and in a fit of grief, he and his wife Niu Yun engage in a battle of wits.
Three free and romantic young people live a life with their own thoughts: some are eager to get rid of singleness, some want to debauch before getting married, some want to gain a foothold in the big city. Because of an emotional derailment, the three kinked into a mess of "joking and scolding". When various values collide, when a person needs to balance family friendship and love...their chaotic life is like half a comedy.
