Christmas Movie too Good For The Hallmark Channel

It's Undercover Christmas, with Jamie Gertz (anyone remember her from Square Pegs with Sarah Jessica Parker as the nerdy high schooler?) as a cocktail waitress / witness being protected by an FBI agent while having Christmas at his parents' house. I would have bought a copy of it long ago if I hadn't remembered the title incorrectly as House Arrest Christmas. Pretty close, but not close enough to find it on Amazon.
