Sullivan's Crossing has returned for its highly anticipated fourth season, bringing unexpected drama as Maggie's secret husband, Liam, enters the scene.
The series, based on Robyn Carr's novels, follows neurosurgeon Maggie, played by Morgan Kohan, as she navigates life in rural Nova Scotia while reconnecting with her estranged father, Sully, portrayed by Scott Patterson.
The previous season set the stage for tension between Maggie and her love interest, Cal, played by Chad Michael Murray. Season 3 introduced conflicts when Cal expressed a desire to take their relationship further, while Maggie hesitated. The revelation of Liam, played by Marcus Rosner, as Maggie's husband shocked both Cal and viewers alike.
As the series progresses, viewers will witness how this unexpected twist impacts the dynamics among the characters.
Showrunner Roma Roth expressed her excitement about the new season, sharing, "I'm absolutely thrilled that Sullivan's Crossing is returning for a fourth season... Season 4 will explore themes of change and transformation."
