According to the synopsis of the episode, Chief Boden finds himself in the middle of a fiasco concerning a female neighbour, who he believes is setting him up.

Severide, who is still on probation following his altercation with Captain Patterson, receives a surprise visit from his father and discovers some interesting information on Patterson that could be a game-changer. Meanwhile, romance blossoms at the Chicago Fire Department gala.

As mentioned in the synopsis, Severide is still under grounded after a dispute with Patterson. Therefore, Patterson gets his old post in the fire department and replaces Severide as the leader of Rescue Squad 3.

Meanwhile, Severide's father Benny, a former colleague of Patterson, reveals some information to Severide that shocks him.

Elsewhere, Chief Boden is in trouble as his new female neighbour (Ilfenesh Hadera) has accused him of something serious.

Boden believes the accusations are meant to frame him for a crime he never committed, and he is determined to clear all the misconceptions.

The annual Chicago Fire Department Gala is about to take place, and the couples in the department will be seen romancing each other.

In the previous episode, titled "2112", Cruz was visited by a gangbanger who knew his brother. In other events, the team responded to a call that involved an 18-wheeler and was thanked with tickets to see Rush.

Meanwhile, Severide was upset because Patterson was treating him like a normal candidate when he was a former head of Rescue Squad 3. Severide thought he had already proved his skills as an efficient firefighter and didn't need all the basic training.
