After her sister is brutally murdered, bubbly younger sibling Mahek (Tanisha) withdraws from her friends and family into a protective shell. The only boy she's remotely drawn to is a college student who's much like Mahek is now -- shy and introverted. Things seem to be proceeding smoothly between the two, until one day when Mahek is attacked by a man in a joker's mask who seems intent on murdering her.
