On a dark and windy night, on a speeding train, the sleeper car should be a peaceful place to rest.However, for a doctor preparing for an important interview, it was a sleepless night full of twists and turns.

Xiao Li, a young and promising doctor, finally got the opportunity to interview for the position he has long dreamed of after one and a half years of hard work and unremitting preparation.In order to meet this challenge in the best condition, he boarded the train to the interview location in advance, intending to recharge his batteries in the sleeper car to ensure that he could face the judges with full energy the next morning.

However, fate did not seem to favor this hard-working doctor.In the carriage, a group of passengers of all kinds broke the tranquility of the night.A drunken drunkard made a loud noise and confided his unhappiness to no one else; a couple preparing to attend their daughter's wedding kept whispering and exchanging the details of the wedding because of nervousness and anticipation; a wandering girl traveling around the world, with curiosityHe looked at everyone in the carriage with his eyes, exclaiming exclamations and questions from time to time.To make matters worse, there is an unknown friend who keeps disturbing the doctor and trying to have meaningless chats with him.

These disturbances made it impossible for Xiao Li to sleep peacefully. He tossed and turned, feeling anxious.He understands that if he cannot take a good rest, tomorrow's interview will be seriously affected.However, no matter how hard he tried to adjust his mentality, the noise around him always lingered.

Just when Xiao Li was almost desperate, a burst of frightened screams suddenly broke out in the carriage.Everyone woke up from their sleep and saw a body falling on the bed opposite!This sudden change plunged the entire carriage into chaos and panic.

Xiao Li was also frightened by this scene and his heart beat faster, but he quickly calmed down.As a doctor, he knows the importance of staying calm in such situations.He quickly observed the condition of the body and tried to communicate with other passengers to understand what happened.

After some investigation, Xiao Li discovered that the body turned out to be a passenger who had interacted with them in the carriage before.What shocked him even more was that the cause of death of this passenger seemed to be inextricably linked to other passengers in the carriage.

Faced with this bizarre incident, Xiao Li decided to temporarily put aside his personal troubles and anxieties and work with other passengers to uncover the truth of the incident.They began to recall all the previous details and look for clues and evidence.

After some efforts, they finally discovered the truth hidden behind the incident.It turned out that the deceased had different entanglements and grievances with other passengers in the carriage during his lifetime, and these entanglements eventually led to his unfortunate death.
