Kathryn Liu (Parrish) is an antiques buyer for her father's store and has been happily dating Rob Ashford (Lissing) for nearly a year. When he surprises her with a pre-Christmas proposal, her fear of a failed relationship sends her dashing away without giving him an answer. Heartbroken, Rob drives to his sister's house and has a car accident that leaves him without memories of the past year, including his relationship with Kathryn and his once-infectious love of Christmas. Following the unconventional orders from his doctor, Kathryn agrees to help trigger Rob's memory by retracing their romance and reintroducing him to the holidays. But as his memories inch closer to returning, Kathryn must face the painful truth that bringing Rob back to himself may mean losing him forever, unless she can finally find the courage to fight for the love she was too afraid to claim.
