When it comes to holidays, Minnesotans rise to the occasion -- and the little town of Lake Eden is baking up a storm with Hannah Swensen leading the way. The annual Christmas Buffet is the final test of the recipes Hannah has collected for the Lake Eden Holiday Buffet Cookbook. — The recently divorced Martin Dubinski arrives at the buffet with his new Vegas showgirl wife -- all wrapped up in glitter and fur. His ex-wife, however, seems as cool as chilled eggnog. And when Hannah's mother's antique Christmas cake knife disappears, its discovery in the decolletage of the new -- and now late -- Mrs. Dubinski puts the festivities on ice.

With everyone stranded at the community center by a blizzard, Hannah puts her investigative skills to the test, using the ingredients at hand: half the town of Lake Eden -- and a killer. Now, as the snowdrifts get higher, it's up to Hannah to dig out all the clues -- and make sure that this white Christmas doesn't bring any more deadly tidings.
