On Christmas Eve, Kristin, played by Shiri Appleby, is stuck in a joyless rut, haunted by a family holiday from her teenage years that went spectacularly wrong and set her on a path of emotional distance. When she wakes up, she finds herself mysteriously transported back in time to that very Christmas, forced to relive the pivotal moments that fractured her relationship with her mother, portrayed by Elizabeth Mitchell. Armed with adult hindsight and a sharp, often sarcastic perspective, Kristin sees her younger self and her family's dysfunction through new eyes. As she attempts to rewrite the past without erasing her own future, she clashes with her rebellious teen self and finds an unexpected romantic spark with a kind-hearted local, played by Will Kemp. This heartwarming comedy, directed by Jim Fall, blends witty time-travel antics with genuine emotional stakes, asking whether revisiting old memories can heal present wounds and, ultimately, if you can truly go home again for the holidays.
