Name of the Episode: “Nobody Else Is Dying Today”

Casey is still knee deep in his Alderman duties, which is interfering with taking care of Louie. He keeps his appointment to view a toxic containment warehouse; but his simple trip turns into a dangerous event to stay alive. One of the foreman’s accidently pierces a toxic bin and allows the fumes/liquid to escape. The foreman passes out from the fumes and Casey drags him into the break room. While another worker is not so lucky, he falls into the toxins and his skin burns. The manager runs outside to call 911 while Casey, the foreman and the foreman’s daughter are trapped in the break room.

Laurel is traumatized at the thought someone died from the acid that’s been released. Her father for the moment is breathing on his own and his injuries do not appear to be life threatening. Mouch and Brett meet with a publisher at the station; but their deal goes south when the executive says they need to pay $5,000 up front to help cover expenses. They’re disappointed with the proposition, but can’t dwell for long because Brett is called away. Casey is wondering why he hasn’t heard any sirens outside. He peeks through the window and sees Gary tried to run back to his office before going outside. The fumes got to him first and he never called 911. Casey knows no one is coming now because there is no cell signal in the break room. Just then, the fumes begin to creep under the door!

Back at the firehouse, Otis reveals to the team he has been short listed for a civilian mission to Mars. Cruz is the only one who believes in him, while everyone else just laughs at his endeavor. At the warehouse, Laurel’s dad wakes up and admits his boss has been cutting corners to make money on the side. The only hope they have is to send Laurel through a vent to the office next door to call for help. However, the fumes have already leaked into the office, so they try desperately to seal off the vent. Another problem occurs when Casey sees the acid going towards some aluminum shavings, which will cause a chemical explosion. The aluminum begins to hiss and the electricity sparks prompting Laurel to panic even more. Casey calms her down and orders her to climb through a hole he busted open. She is able to escape and call for help. The firehouse finally gets the dispatch call and goes onto the scene. The electrical system is proving to be quite difficult to shut off, which causes more issues for the team. Casey is struggling to breathe and keep Ken alive; the squad is able to get Ken and Casey out safely.

At the end of the episode, Cruz admits he made up the whole Mars mission as a prank. Otis had already caught on, and pranks him right back. Just after, Trudy barges into Molly’s demanding to speak with Brett. A phone mix up lead to Trudy to find out they’re trying to publish a romance novel. Trudy gently reminds Mouch she has a friend in publishing that can read their manuscript immediately.

On next week’s episode, Severide and Casey are at war over a suspicious fire. Casey believes a husband is guilty of setting fire to an apartment with his wife present. While Severide believes, the husband is innocent; whose side will you take? Find out next week when we post another after take!
