Up and coming female astronomer in New York crunches data and figures out there is a 78% likelihood a yet undiscovered meteor shower event will take place on one of five days leading up to Christmas. And the prime viewing location is a peak just outside a small upstate community. So she gets clearance and takes a telescope with her to the location. (All filmed in Canada.)
Once there she finds a mixup with hotel reservations and is aided by a local family that own and run the hotel, she is put up and befriended by all of them, including a nice man who has been told his ranger job is being eliminated for lack of funding. As things unfold and complications with the Christmas festival and its bright lights make things a bigger challenge, the astronomer and the ranger begin to take a serious liking to each other.
My wife and I watched it at home on Amazon streaming. It is a cute story with attractive people, very much like a Hallmark movie. Just don't take any of the highly flawed astronomy seriously. Plus, they even got "reflector" and "refractor" telescopes mixed up in the dialog. But hey, it's just a movie.
