The first scene in Night Agent features a mother boarding a train with her small daughter. The train is full, so a man gets up and offers them his seat. The man notices a stranger leave a bag behind as he stands up and is wearing a black jacket and hoodie. He advances to look inside the bag and discovers a bomb.

After he releases the emergency door, he suddenly stops the train. He pulls out his FBI badge and tells everyone to get off the train slowly. When there is a bomb threat, chaos ensues. The majority of passengers succeed in leaving the train before the bomb goes off.

The FBI agent gets information that one individual dies before paramedics and the appropriate authorities arrive. Our protagonist is getting first aid when he spots the bomber lurking in the throng, watching in secret.

A struggle breaks out as the agent pursues the stranger through some shadowy alleys. The agent notices the man has a serpent tattoo on his side as they fight. The suspect evades capture once more despite his attempts to arrest him. The FBI agent is hit by a car as they start another pursuit, but the suspect escapes.

Another young person, Rose, is anxiously anticipating giving her first TED talk. She appears to be a significant player in the cybersecurity industry. She is approached by another woman who hands her some financial forms to sign. They are both happy that they were able to accomplish their goal.

After that, we jump ahead a year. We discover the FBI agent's name is Peter from this point on as he gets ready for his shift in the White House. He is summoned to a meeting with his boss, Diana Farr when he arrives. She is not happy with his reaction to Elliot Rome's ambush, who accuses him of being responsible for the bombing a year prior.

In the future, Farr advises him to practice declining to comment during ambush interviews with Elliot Rome. She reminds him of their agreement and that he must pass the time as a night agent before moving on to something greater. She informs him that she is departing for Maryland and requests that he annotate certain documents for her. He says "goodbye" and walks away.

Ben Almora, who he encounters on the way to his office, lets him know that the President is looking forward to their pickup game. Ben suggests that the President has an interest in Peter's decision to stay with the FBI rather than join the secret service. Another man, Hawkins, joins them and inquires about a crime report that Peter was to write.

Peter's justification does not go well with Hawkins, who declares that the report was "need to know." He finds it annoying because Peter reports to Farr, the chief of staff for the president. Jesus cautions Peter to choose his side wisely. Peter enters his windowless office, which has just a phone and a table and gets to work on some paperwork.

On the other side, Rose warmly accepts his uncle Henry and aunt Emma. She explains that the board dismissed her. She explains what happened and that she has remain with them because she is bankrupt throughout dinner. It seems that her organization experienced a data breach, and as a result, she lost everything. Her aunt and uncle try to uplift her and reassure her that everything will be alright. They are happy to assist her because she is family.
