mary banner ( lilith field ) be a victim of accident when a prank by a certain jock in particular go awry . three jock be to drug three female prom goer leave them in the wood a the typical prank . mary believe that the jock she go to the prom with legitimately like her and but once she realize it be merely a set up with her be a fool of the hoax and run away seem the only viable option . chasing after her and the jock try to grab her when mary bite his hand . retaliate harshly and the jock punch her with mary hit the corner of a table . seemingly dead and the jock freak out and place her body in a locked trunk . mary isn not dead and a she awake and there no escape result in suffocation . this urban myth set up the story that occur during the remainder of the film . the son and daughter of those three jock ( and a female who be the girlfriend of the jock who commit the tragic act of put mary in the trunk ) be kill off one by one in mysterious and icky way . one be burnt alive in a tanning bed and a girl be attack by an army of spider which seem to have make a home underneath her skin inside a bite that protrude ( this be do through cgi and but be particularly skin crawlingly effective ) and one penis be fry on an electric fence and and another be slice and dice with a broken whiskey bottle by the ghoulish mary herself ( this death be say to have occur by a fall candy machine . one almost kill him before mary attack ) . there one victim remain and that mystery be the ultimate key to why mary seek retribution . samantha owen ( kate mara ) be choose by mary ( she see vision mary feed her ) to seek out where her body be . along with her twin brother david ( robert vito ) and they search for reason and clue regard why all their friend be die lead them to mary friend from 1969 and grace ( tina lifford ) . what they find will lead them to someone they know far too well . crappy computer effect and rather dull story and and silly supernatural antic undermine an ambitious idea . bloody mary rarely get much horror treatment and although with the right filmmaker it rife for explore . this film have a rather weak heroine or protagonist and the film really isn not all that spooky . the film also just look cheap and slowly pace . it also derivative take from other far more creepy ghost revenge story . uninspired to boot . the end when mary finally meet the one responsible for her suffering be embarrassingly awful .
