The shooting of a child in their neighbourhood forces Cruz and his brother to think about the gang, Isabella gets Mills to dress up for a gala, Casey feels sad he will be seeing Dawson less, and Shay gets in deeper with Devon.

The Firehouse 51 crew has a Thanksgiving to remember when drugs, a car accident, and a gang shooting get in the way of traditional holiday pastimes.

The crew of Firehouse 51 are full of festive cheer until Casey is accused of stealing a diamond necklace. Meanwhile, sparks fly between Shay and Severide.

Casey's conscience gets put through the wringer when he visits his mother in prison. Cruz shares a secret, and Pete fills in for Shay in the ambulance crew.

Severide is made an enticing offer by a woman he saved from a car crash and the crew bid farewell to a colleague after a blaze at a garage.

Severide finally addresses Chief Boden about his injury and makes some important personal decisions about his future. Meanwhile, Casey struggles with family matters and Dawson takes matters into her own hands.
