Episode 1

Under the dim lights of the police station, Martin sat at an old table, facing the serious police officers.They asked him to talk about Cole, the partner who was usually taciturn but could always provide key clues at critical moments.Martin closed his eyes and recalled the case in 2012. At that time, he and Cole were still rookie detectives, facing a difficult criminal case together.

Martin described the investigation process in detail, how he and Cole approached the truth step by step, and how they faced complicated clues and elusive suspects.He also talked about his thoughts on Cole, a partner who always seems a bit out of touch but always offers unique insights.

However, life outside the police station is completely different from the tense atmosphere inside the police station.Martin recalled one time when Cole came to his home with flowers. What was originally a friendly visit turned into an embarrassing scene because of Martin's ridicule.Cole left angrily, and Martin realized his mistake, but neither of them tried to repair the rift.

The next day, the two drove to a remote village to investigate the case.In the car, they discussed various ideas, and Martin was surprised, even a little grateful, that Cole spoke today after not speaking for three months.However, Cole fell into silence again, just staring out the window silently.

In the police station, Martin and Cole's work is still tense and arduous.The chief arranged for them to manage the incident room, and the two worked together. Martin was responsible for organizing documents, while Cole was responsible for going out to investigate.During an investigation, Cole tried to obtain information about the case from a bar girl, but failed.

When Martin returned home, he felt distraught when faced with his wife's concern and the expectations of his children.He couldn't forget the cases in the police station, nor could he forget the delicate relationship with Cole.And when he learned that there were no fingerprints on the deceased and that someone had administered methamphetamine or LSD before his death, he became even more determined to find the truth.

Martin and Cole once again returned to the vicinity of the crime scene to investigate. They interviewed local residents and looked at church patterns, looking for any possible clues.After returning to the police station, they told the chief the information they had investigated and got a new clue - a vague portrait.

As the case progresses, the relationship between Martin and Cole gradually changes.They began to understand each other better and respect each other's way of working.Martin also began to reflect on his attitude towards Cole and tried to make up for past mistakes.
