A young woman's quiet night in becomes a free-fall into fear in this disturbing home invasion thriller. After she lands her dream job, a young cellist (Louise Linton) settles in for a relaxing few days holed up in her apartment-but as a violent storm rages outside, she can't shake the feeling that someone is watching her every move. Cleverly toying with the rules of suspense, director Travis Z wrings maximum terror from everyone's worst nightmare: you may not be alone.
