“A Merry Little Ex-Mas” (2025) is a warm, funny, and emotionally heartfelt holiday romantic comedy that follows the chaotic reunion of two ex-lovers who never expected to cross paths again — especially not at Christmas. The story centers on Holly Carter, a driven event planner whose life revolves around work, deadlines, and avoiding anything that reminds her of her past. When she’s assigned to organize the annual Winter Lights Festival in her charming hometown, she reluctantly returns, hoping to complete the job quietly and leave before old memories catch up to her. But her plans fall apart the moment she discovers that the festival’s new co-organizer is none other than her ex-fiancé, Jack Sullivan.

Holly and Jack’s breakup years earlier was messy, painful, and unresolved. Both believe they’ve moved on, yet the forced partnership immediately reignites buried emotions and sharp tensions. They clash over every detail — from decorations to budgets — as their old dynamic resurfaces in humorous and sometimes explosive arguments. Despite the bickering, the magical holiday atmosphere of the town, combined with their shared history, begins to soften the walls they spent years building. Little by little, they’re reminded of the reasons they once fell deeply in love.

As the festival preparations intensify, Holly reconnects with old friends and finds solace in the warmth of her community, something she didn’t realize she missed. Meanwhile, Jack struggles with his own vulnerability, revealing that he never entirely healed from their breakup. The deeper they dive into the project, the more obvious it becomes that unresolved misunderstandings — not a lack of love — tore them apart. Their chemistry grows harder to ignore, and moments of unexpected tenderness begin slipping through the cracks.

Complications arise when Holly’s ambitious new boyfriend unexpectedly arrives in town, hoping to surprise her and pull her back into her fast-paced city life. His presence forces Holly to confront the uncomfortable truth: the life she built after leaving Jack may not be the one she truly wants. Jack, in turn, faces the possibility of losing her again and wrestles with whether to fight for a second chance or let her go.

The Winter Lights Festival becomes the emotional turning point as a series of mishaps throw Holly and Jack together during a snowy Christmas Eve crisis. In the midst of chaos, they finally confront their past with honesty, uncovering the misunderstanding that shattered their relationship and realizing that love never fully left.

“A Merry Little Ex-Mas” (2025) delivers a charming blend of romance, humor, and holiday magic. It’s a story about rediscovering the courage to love, forgiving old wounds, and finding joy in the most unexpected reunions — wrapped in twinkling lights and the warmth of Christmas spirit.
