Four interwoven stories that occur on Halloween: An everyday high school principal has a secret life as a serial killer; a college virgin might have just met the one guy for her; a group of teenagers pull a mean prank; a woman who loathes the night has to contend with her holiday-obsessed husband.

Michael Dougherty’s (“Superman Returns,” “X2: X-Men United”) new horror movie, produced by Bryan Singer. “Trick ‘r Treat” is four interwoven stories that take place on Halloween with such characters as a staid high school principal who is a Halloween serial killer, a college-age virgin seeking that special guy, a woman who hates dressing up for Halloween and whose husband is obsession with the holiday and a group of young teens who pull a cruel prank.

It is said that Halloween is the night when the dead rise to walk among us and other unspeakable things roam free. The rituals of All Hallows Eve were devised to protect us from their evil mischief, and one small town is about to be taught a terrifying lesson that some traditions are best not forgotten.

Nothing is what it seems when a suburban couple learns the dangers of blowing out a Jack-o-Lantern before midnight; four women cross paths with a costumed stalker at a local festival; a group of pranksters goes too far and discovers the horrifying truth buried in a local legend; and a cantankerous old hermit is visited by a strange trick-or-treater with a few bones to pick.

Costumes and candy, ghouls and goblins, monsters and mayhem… the tricks and treats of Halloween turn deadly as strange creatures of every variety-human and otherwise-try to survive the scariest night of the year.
