"Shiela" (Kaley Cuoco) has an unique gift. She can travel through time. Now only for a very limited amount of time, but enough to influence the lives of those close to her. She meets "Gary" (Pete Davidson) and what ensues for the next ninety minutes is a messy drama that demonstrates how they fall for each other and how she tries to use her powers to make his/their life better. Of course it doesn't all go to plan, there are lots of pitfalls and boy are we made to suffer them all too! The story does have an interesting premiss - what might we do to help our loved ones deal with - or avoid - trauma, but neither actor here really manages to draw the audience into this really lacklustre and extremely verbal series of shallow scenarios that end, well - you do not need to use any more imagination that the writers did to arrive at that. It is frequently quite cringe-making, and in the end I really couldn't have cared less whether they did or didn't get run over by Santa's rogue sleigh. Very mediocre Christmas television fayre, this - and instantly forgettable.
