The CW will premiere the fourth season of the Canadian drama Sullivan's Crossing on April 20. The new episodes center on Maggie Sullivan's renewed commitment to Cal, disrupted by the arrival of her ex-husband Liam with a shocking revelation. A first teaser trailer highlights Maggie's difficult choice between a vow and her chosen life.
The CW has announced that season 4 of Sullivan's Crossing, adapted from Robyn Carr's best-selling book series, will make its U.S. debut on Monday, April 20, at 8/7c. The series follows Maggie Sullivan, played by Morgan Kohan, as she navigates life in the small town of Sullivan's Crossing.
According to the official logline, Maggie's life is stabilizing with a new career direction and commitment to Cal, portrayed by Chad Michael Murray. However, her ex-husband Liam arrives with a revelation that upends everything, prompting Cal to doubt if Maggie can escape her past. The cast also includes Tom Jackson as Frank, Andrea Menard as Edna, and Scott Patterson as Sully.
The first official promo teases Maggie's dilemma: whether to stand by "the vow she made or the life she chose."
This season builds on the third season finale, which aired in July 2025. In that episode, Liam, played by Marcus Rosner, appeared as Maggie's husband—previously described by her as a "summer fling." At that point, Maggie had succeeded in surgery on Edna's brain tumor and reconciled with Cal. Meanwhile, Sully planned a trip to Ireland with Helen, and Rafe and Sydney debated marriage.
Sullivan's Crossing continues to explore themes of personal growth and relationships in a rural Canadian setting.
