This is really a nice little film, few actors, and it unfolds slowly. We meet Paul, who has rented a cabin on a lake to try and finish his book, and his wife Deb comes along. They are older, and there is some controversy about what he is writing and trying to expose. On the way to the cabin, they get a flat, and within minutes the sheriff shows up to help him. You know that isn't how reality works. Anyway, the title comes from his bringing along his ant farm, as watching the ants at work relaxes him. But there doesn't seem to be anyone around. One morning he falls from the dock through the ice, and the sheriff shows up to rescue him. Another morning, he looks out onto the frozen lake, and there is a young woman on the ice who they rescue. She is the exact age of the daughter they lost, and she seems not to know who she is or how she got there. And they start to hear strange noises outside. Paul needs to make a longer trip, but he finds no matter which way he went, he winds up at the cabin. What is going on? It is really nice, with no spectacular CGI effects. Just an unfolding mystery.
