The episode starts with Kelly Severide in the shower. Stella Kidd (Miranda Rae Mayo) takes notice and says his recent behavior is rather strange. Also, she questions why he doesn’t want to help her with the pending exam. Kidd fears Severide is growing distant, leaving a void between them. Chief Wallace Boden is assigned to clean an abandoned building. Severide volunteers to go with him, alarming Stella in the process. 

Meanwhile, the firehouse received an emergency call about a billboard falling on a truck, leaving the driver trapped inside. While on the scene, the driver takes a liking to Matthew Casey (Jesse Spencer) and proceeds to flirt with him. For instance, she jokingly admits to working at the strip club the billboard advertised. Ironic right?

While expecting the abandoned building, Severide and Boden discover they’re not alone. They find an unidentified man that utters the numbers, “24198.” They proceed to ask for a name, but the man repeats the numbers. So, what does the five-digits mean?
