Despite the glowing gas lights, festive wreaths, and holiday cheer that covers the town of Worthville, Catherine Todd is far from being in the Christmas spirit. She continues to wrestle with the losses that shattered her heart two years earlier, and while shopping for her kids, her overreaction to a disappointment confirms what she already knows―she's stuck in her grief. Children's book author Collin Donnelly shows up in Worthville for a signing, but when an abrupt first interaction with local resident, Catherine, doesn't go well, he wonders if he made a mistake coming to this small town. Eager to make amends, he soon learns they share a common interest in birding, and he invites her on an adventure that turns out to be filled with unexpected wonder for both of them. They soon find themselves working together to save an endangered bird, and the more time they spend together, the more Catherine is drawn to Collin. But there are forces mounting against them having a relationship, including Catherine's reluctance to embrace the future, a difficult secret in Collin's past, and an alliance Collin has with his agent, who clearly doesn't want to remain his former girlfriend. Can they trust that, through God, there really is a season for everything?
