Holly finds her world turned upside-down when she suddenly finds herself incapable of lying. (Don’t you hate when that happens?) It’s because of a wish her niece made to Santa Claus. And now, with Christmas coming up fast, she has to come to terms with her natural penchant to want to fib while trying to do the right thing. And that’s no lie.

A singer and her dog move next door to a widowed father, his little girl and her cat. Despite a rough start, the neighbors grow close, just in time for a Christmas wish to be granted thanks to their devoted pets.

When little Lucy wishes it were Christmas every day, "forever and ever", her dad tells the cautionary tale of her grandmother Tilly, who, as a little girl, made the very same wish, and the dire consequences that occurred after her wish was granted.
