At a Christmas party, Miranda, dresses as Mrs. Claus and Paul dresses as Mr. Claus. They have a great night but accidentally get separated without finding out who the other really is. Both are app developers with competing apps to help people find perfect gifts to give. They have completely different attitudes to what are perfect gifts and they really dislike each other when they meet in work life without knowing that they have met before. Suddenly their respective companies are bought up by the same group and they are forced to work together against their will. At the same time, they try to get in touch with Mrs. and Mr. Claus, who they, on the other hand, really liked.
It's okay, even if it feels a little doubtful at the end.
