“Sullivan’s Crossing” is back for Season 4 — with cliffhangers, tough choices, and a shocking relationship twist that could change everything.

Sullivan’s Crossing is officially returning for a fourth season, and fans couldn’t be more excited to see what’s next for Maggie Sullivan’s journey through love, career, and the complicated ties of her Nova Scotia hometown. The hit drama, based on the bestselling Robyn Carr novels, has built a devoted audience by blending heartfelt romance with small-town intrigue, and after the Season 3 finale left viewers with multiple cliffhangers, Season 4 promises even more emotional twists — including an unexpected relationship revelation that could change everything.

The series follows Boston neurosurgeon Maggie Sullivan, played by Morgan Kohan, whose life is turned upside down by legal troubles that send her back to her childhood home. There, she reconnects with her estranged father, Harry “Sully” Sullivan (Scott Patterson), and finds herself drawn to newcomer Cal Jones (Chad Michael Murray). Maggie’s return is anything but simple, as she navigates professional dilemmas, personal growth, and complicated romantic entanglements. As showrunner Roma Roth explained, Maggie’s arc has always been about balance — finding a way to merge her ambitious career with the deep emotional connections she rediscovers in Sullivan’s Crossing.

Season 3 deepened those themes, weaving together Maggie’s professional battles with her growing relationship with Cal, while also exploring Sully’s own struggles and the bonds between the town’s residents. By the time the credits rolled on the finale, Roth’s earlier tease of a “big shoe drop” proved prophetic. The final moments hinted at secrets and shifting loyalties, setting the stage for high drama in the next installment. One of the most talked-about implications? A surprise development that could shift the romantic dynamics entirely, possibly involving a revelation that Maggie — and the audience — never saw coming.

The cast for Season 4 has yet to be officially confirmed, but given the emotional weight of the cliffhangers, it’s expected that key players will return. Kohan, Murray, and Patterson are almost certain to reprise their roles, alongside Tom Jackson as Frank Cranebear, Andrea Menard as Edna Cranebear, and Allan Hawco as Andrew Mathews. Patterson has spoken passionately about the series, calling it one of the most important projects of his career, offering him a chance to bring a new vulnerability to the screen. Murray, too, has described the show as more than a romance — a place where characters, and viewers, “go to heal” and “slow down to really live.”

Season 4 will likely pick up immediately after the finale’s revelations. Roth has hinted that the series thrives on push-and-pull tension, meaning Maggie will face new challenges that test her personal relationships as well as her professional goals. The unexpected relationship twist teased by insiders could create ripple effects not just for Maggie and Cal, but for the entire community of Sullivan’s Crossing. If past seasons are any indication, these changes won’t come without difficult choices and emotional consequences.

Part of the show’s appeal lies in how it blends these personal dramas with the scenic charm of Nova Scotia, using the backdrop of the small town to highlight themes of belonging, second chances, and reconciliation. Season 4 will almost certainly continue to explore these ideas, especially as Maggie is forced to confront what — and who — truly matters to her. The balance between career and personal life has always been her central struggle, but now, the equation may change entirely if the hinted revelation challenges her current path.

While no release date has been announced, the production timeline suggests that fans could see the new season sometime in late 2026, depending on filming schedules. In the meantime, Season 3 is streaming on Netflix, allowing newcomers to catch up and long-time fans to rewatch the intricate web of relationships that will shape the next chapter. With Roth promising that “there’s never a dull moment at Sullivan’s Crossing,” anticipation is high for how these new developments will unfold.

For now, viewers are left to speculate on the nature of the relationship revelation — whether it’s a hidden past, a romantic betrayal, or a surprising new pairing that challenges the status quo. Whatever it turns out to be, it’s clear that Season 4 will not only continue Maggie’s story but also redefine it, offering fans the emotional depth and dramatic twists they’ve come to love from Sullivan’s Crossing.
