The One Chicago universe is gearing up for its Fall 2025 return with a season packed with jaw-dropping developments, according to the first official One Chicago trailer.
Among the biggest surprises — a mysterious pregnancy storyline involving Dr. Hannah Asher (Jessy Schram) on Chicago Med, with speculation around who the father might be as hinted in the latest promotional material.
Fans also got their first look at Brandon Larracuente joining Chicago Fire Season 14 in a key role that producers are keeping tightly under wraps, promising “new heat” for Firehouse 51.
Meanwhile, Chicago P.D. teased ongoing drama in the Intelligence Unit following recent changes to the team, and Burgess’s married life with Adam Ruzek continues to be a focus.
The forthcoming season is shaping up to be one of the most emotionally charged yet, filled with family developments, professional tensions, and mystery across all shows in the franchise.
