A failed mission causes conflict for Casey (Jesse Spencer) and Severide (Taylor Kinney) in the next episode of "Chicago Fire" season 5.

In the episode titled "I Held Her Hand," Casey's effort to rescue a woman trapped inside her burning house will fail. But the firefighters will have a bigger problem while investigating the cause of the incident since Casey and Severide will find themselves clashing with each other about the possible involvement of the woman's husband in the house fire.

Both lieutenants have strong opinions about the possible participation of the husband to the fire, and none of them is expected to back out easily. Will this cause a rift between the long-time friends and colleague?

Meanwhile, Hermann (David Eigenberg) will try to pin down the mystery tagger who continues to violate the firehouse. Will Hermann finally catch the perpetrator?

On the other hand, Dawson (Monica Raymond) and Brett (Kara Killmer) will be dispatched to rescue a teenage boy after his supposed romantic homecoming proposal turned into a huge tragedy. The two are expected to reach the area in time to save the 16-year-old boy from his injuries.

The upcoming episode will also feature an unexpected visitor who will show up to surprise Boden (Eamonn Walker). Although, the reason for the surprise visit remains a mystery.

However, viewers of the action drama series will have to wait a little longer before they get to watch the fifth episode of "Chicago Fire" season 5. The series will take a short hiatus after the airing of episode 4, titled "Nobody Else is Dying Today," on Tuesday, Nov. 1 and will be off the air in its usual time slot next week. But the series will only be gone for a short time since NBC is scheduled to air the episode 5 of "Chicago Fire" season 5 on Tuesday, Nov. 15.
