Tensions run high between Casey and Herrmann when the firehouse responds to an apartment complex fire. After discovering something extremely suspicious during the call, Kidd and Severide do some investigating and get CPD on the case.

Firehouse 51 tackles a fire caused by a dropped jet engine, and one of their own is accused of a theft related to the incident; Kidd and Boden disapprove of Kylie's potential new love interest.

When Firehouse 51 is called to the scene of a dangerous blaze inside a 10-storey storage unit, Herrmann and Cruz find themselves trapped inside a freight lift with all communications cut off.
