The world of Grey's Anatomy and Station 19 is more intertwined than ever.
To kick off 2020, both shows will stage another two-hour crossover event that will also serve as the third season premiere for Station 19.
If you watch Grey's Anatomy online, you know Grey's Anatomy Season 16 Episode 9 concluded in epic fashion.
There were twists, turns, and everything in-between.
What the installment did well was set up this crossover.
In the final moments of "Let's All Go to the Bar," Jackson, Richard, Nico, Ben Captain Pruitt, Levi, and other interns were all put in a deadly scenario.
In a twist of fate, a car smashed into the bar, leaving those characters fighting for their lives.
This crossover has the potential to shake up the lives of everyone associated with Grey Sloan and Station 19.
The trailer shows characters battling to stay safe in the face of one of the most harrowing scenarios to date.
Grey's Anatomy has famously killed several cast members off over the years, but the deaths have been more subdued over the last few years.
Will that change with the crossover?
It's possible. Many Grey's faves are trapped in the bar. Then there are the Station 19 characters.
For fans of both shows, this is going to be a pulse-pounding installment.
Grey’s Anatomy stars Ellen Pompeo as Meredith Grey, Justin Chambers as Alex Karev, Chandra Wilson as Miranda Bailey, James Pickens Jr as Richard Webber, Kevin McKidd as Owen Hunt, Jesse Williams as Jackson Avery, Caterina Scorsone as Amelia Shepherd, Camilla Luddington as Jo Wilson, Kelly McCreary as Maggie Pierce, Kim Raver as Teddy Altman, and Giacomo Gianniotti as Andrew DeLuca.
This special event also marks the first time in several years that Grey's will be airing in the 9 pm slot.
The Alphabet network confirmed Thursday that Grey's is moving back an hour to give the Thursday lead-off spot to Station 19.
As a result, the final episodes of low-rated How to Get Away with Murder have been banished to April while A Million Little Things takes over the slot.
Have a look at the crossover trailer below.
