To save the capital-ruptured agricultural science laboratory, researcher Lin Xi sets up a "plant emergency" stall at Xingguang Apartment. Facing Su Man, an anxious white-collar worker who overwaters, an internet celebrity who creates counterfeits with dyes, and a wealthy businessman who is superstitious about pesticides, he insists on using hard data to expose the soil crisis of withered plants. In each first aid that breaks prejudices, Lin Xi must not only overcome the residents' various obstructions, but also tries to use the laws of nature to awaken the instinctive vitality of plants. Facing heavy resistance, this stubborn doctor must find a lifeline for his own laboratory while healing the anxious inner selves of urbanites.
