Episode 14 of 9-1-1 Season 8, titled “Sick Day,” airs April 10, 2025, on ABC—and it's already being called one of the most intense episodes of the season.
The first installment of a two-part event called Contagion, the episode throws the 118 into chaos when they respond to a fire at a biomedical lab storing lethal and exotic viruses. What begins as a routine call quickly spirals out of control after a massive explosion traps Bobby (Peter Krause), Hen (Aisha Hinds), and Chimney (Kenneth Choi) inside the sealed facility.
Outside, Buck (Oliver Stark) and Athena (Angela Bassett) must race against time to coordinate rescue efforts—while also preventing a deadly virus from leaking into the public. It’s a high-stakes mission that tests not just their skills, but their courage, loyalty, and emotional resilience.
The official trailer for “Sick Day” teases an episode full of tension, heroism, and split-second decisions. True to 9-1-1’s reputation, the drama doesn't just come from explosions and danger—it’s the emotional weight, the impossible choices, and the human spirit that hit the hardest.
Fans can expect cinematic visuals, powerful performances, and plot twists that raise the bar for the series. “Sick Day” isn’t just about a viral outbreak—it’s about sacrifice, survival, and the strength of the team that holds it all together.Â
