It’s been five years since the last three-part Chicago Fire, Med, and P.D. crossover. This one did not disappoint.

Chicago Fire, Chicago P.D., and Chicago Med’s first three-part crossover aired on Wednesday, January 29, and it did not disappoint. While the first responders took on a major catastrophe, fans watched as three beloved couples were put to the test.

 

 

The crossover started with Firehouse 51 receiving an urgent call about a fire at the city government building. Chicago Med’s Dr. Frost (Darren Barnet) was at 51 to help the paramedics before he was quickly swept along on the call. Absolute chaos awaited them: An explosion in the building led to a massive fire geyser in the street and a colossal traffic crash, with 50 to 60 victims needing immediate assistance. Violet Mikami (Hanako Greensmith) quickly enlisted Dr. Frost for triage efforts as Firehouse 51 sprang into action.

 

 

It wasn’t long before the P.D.’s Intelligence Unit arrived. Trudy Platt (Amy Morton) and Adam Ruzek (Patrick John Flueger) wanted to know how they could help. After Chief Pascal (Dermot Mulroney) suggested they help with crowd control, Platt recognized Lauren Bates, the government building’s head of security and a former CPD officer.

The firefighters soon faced an unprecedented challenge: Not only had an explosion in the basement destabilized the structure, but a ruptured gas line in the subway system threatened further catastrophe. Even worse, Severide (Taylor Kinney) soon learned that the explosion was no accident and relayed this intel to P.D.

As Platt and Bates reviewed the building security footage to find the perps, Burgess (Marina Squerciati) learned a hard drive with $250 million worth of cryptocurrency was stolen during the incident. After being alerted of two suspects fleeing the building, Ruzek, Platt, and Bates flew into action.

Platt managed to corner one of the perps, but while apprehending him, a mysterious gunman appeared behind her and shot her several times. As Ruzek chased after the other perp, he reported that Platt was down. Platt’s firefighter husband Mouch (Christian Stolte) was devastated by the radio alert, instantly rushing to her last known location.

Meanwhile, Stella Kidd (Miranda Rae Mayo) and Carver (Jake Lockett) discovered a halted subway train filled with passengers. Just after Carver began evacuating passengers, chaos erupted above ground as the building started to collapse. Mouch rushed into the crumbling building to rescue Platt, tearfully carrying her to safety.

Ruzek’s lengthy pursuit of the suspect eventually brought him to the firefighters in the subway. As rubble began falling around them, the perp slipped among the scared passengers to blend in. As Carver rushed above ground with the passengers, Stella and Ruzek urged passengers to stay inside the train until it was safe.

However, just as Carver attempted to return, the tunnel collapsed, stunning the entire fleet of first responders. As Pascal and Severide desperately tried to reach Stella over the radio, Severide ran toward her location, only to find a wall of rubble blocking their path.
