Emergency doctor Lin Yan can see a person's three wrong decisions before death, but can only choose one of them to pursue.
Preventing a decision does not mean death will go away. Medications concealed by family members, doctors' habitual judgments, and a line of records changed by the dispatcher may all become links in the chain of death.
Three years ago, Lin Yan saved the child who had a higher chance of survival in a tunnel accident first, but his sister failed to wait for the next ambulance. A captured video destroyed his career.
Three years later, he returned to Qingwu County Emergency Center. Night shift first aid again and again, all the clues pointed back to the accident.
Lin Yan gradually discovered that the ambulance that his sister did not wait for did not arrive late, but disappeared from the accident record.
