Two Dimensions, One Hotel

Jack Torrance gets a job to look after the Overlook hotel for a few months, and brings along his wife, Wendy, and young son, Danny. But not everything is as it seems. In another dimension, a family nearly identical to them had gotten a chance like this as well. The mother of the family, Jackie Torrance, got a job to look over a hotel for winter, and brings her husband, Wendell, and daughter, Dana.

Apart from being haunted, the hotel is also a portal between the two dimensions. As time goes on, the families notice their reflections are not theirs every now and then.

The story will mostly follow the plot of the movie (not mine), but the twists will come halfway through.
