A stubborn person runs around in an empty city for his lover, a migrant worker who is asking for hard-earned money coincidentally rushes to Wuhan to help, people on the front line of the fight against the epidemic not only have to learn to say goodbye under high pressure, community workers in the rear take care of the residents but leave the risks to themselves, and a father and son who usually neglect communication are forced to spend time together day and night. There are always some unexpected things happening, but there is always a healing seed taking root in people's hearts. This is a movie about spring and hope.
