The season finale of NBC's "Chicago Fire" is almost here.


Spoilers Guide posted a promo video and a brief description of Episode 23 of the third season, "Spartacus." It reports that there will be a fire at a warehouse that endangers the lives of the firehouse 51.

 "Lt. Casey (Jesse Spencer) puts his life on the line and digs deeper into the shady dealings of Jack Nesbitt (guest star Eric Mabius)," according to CaterMatt. "With members of truck and squad at odds over Rice's (guest star Warren Christie) actions in the field, Chief Boden (Eamonn Walker) is left to figure out how to create unity in a divided house, while Severide (Taylor Kinney) comes to question his own judgment."

Carter Matt adds that Boden and Cruz, who is played by Joe Minoso, spring into action and risk their own lives. The episode will also show Monica Raymund's Dawson get news that will change her life.

The season finale will be filled with many surprises as people won't know if another member of firehouse 51 could die until they watch the next show. Rice may be given a larger promotion moving into the next season.

In the last episode of "Chicago Fire," Casey went undercover at a strip club to bust his boss Jack Nesbitt. Chief Voight gets involved with the undercover mission as well.

Sexual tensions remain high between Casey and Dawson after their encounter one night after a few drinks. Sadly, the couple will not rekindle their romance anytime soon. Instead, Casey has been having great moments with a stripper named Katya.

Tune into NBC Tuesday at 10 p.m. ET to catch the season finale of "Chicago Fire."
