Sadie (Kyla Pratt) and Ben (Jarod Joseph) decide to test the theory of whether or not the best friends can fall in love. When they were eight-years-old, they planted a scrawny 3-foot tall Christmas tree behind their church and made a Christmas Pact, but in the years since, their busy lives have threatened to break it. But with a little Christmas magic, each holiday that passes sees not only their tree grow taller and stronger, but also their love.
