[3] In Norwich, England, on December 18, 1334, knight Sir Cole Christopher Fredrick Lyons and his brother Geoffrey participate in an annual Christmas hawking competition.

In the year 2019 on the same day in Bracebridge, a small city in Ohio, high school science teacher Brooke Winters, who is disillusioned by love, agrees to take her niece Claire to the opening of the "Christmas Castle", which is the same place Cole arrives in.

Cole, confused by the new and unfamiliar surroundings, gets hit by Brooke's car by accident, and is taken to the hospital, where Officer Stevens checks his background and assumes that he must have amnesia, as he has no ID and claims to be a medieval knight.

She opens up to him about her late parents and an ex-boyfriend who had left her for someone else years ago, and he slowly shares his own past with her as they grow more familiar.

In his search for the quest given to him by Kayela, Cole ends up rescuing two children in danger on a frozen lake and catches an escaping pickpocket, but does not feel fulfilled.

The website's critics consensus reads: "While its plot borders on the absurd, The Knight Before Christmas is endearing and charming enough to make it a worthy addition to the holiday rom-com genre.
