When Sara gets Rebecca for a roommate, She's getting more than she expected.
Rebecca becomes obsessed with Sara. Sara becomes aware of Rebecca's obsession, but the question is how she'll deal with it.
Not much of a plot beyond the obsessive roommate, but plenty of scary moments. There are no "blood and guts" scenes. There is no objectionable content beyond some mild curses.
It is very suspenseful and entertaining at the same time. Definitely worth seeing.
