MSF: Male Seeking Female (2014)

Sexy 23-year-old Gillian has no trouble attracting men, but her bipolar moods scare them off. Once dumped, her anger knows no bounds. She's on better behavior with man-of-her-dreams Andy, until her boss and mother push her into a corner and Andy's sister dies as a result. The only question now is whether Andy himself will fall prey to the girl he met online.
