Rosemarie Foster is the main antagonist in the movie Girls Gone Dead.  She is the overly religious mother of Becca Foster and is very controlling over her daughter, much like Margaret White.  When Becca spends the weekend at a party house with some friends, Rosemarie and Becca's stalker Todd follow her and begin killing her friends and other "deviants" one by one with a medieval ax.  After the killers are identified, Todd is impaled on his own weapon and Rosemarie burns to death.
