First and foremost the synapse is wrong and is more like "After escaping from a rehab facility in an effort to visit her sick mother, a girl finds herself trapped at a reset stop with 4 others to await the end of a storm, but the storm is not the only thing deadly". Then the movie had so many holes, is very predictable and didnt have a clear cut ending to all the storylines it created.
If you are bored, sitting there with time to kill and have something to do and just want background noise, than this is the movie for you.
