A pack of muscle-headed small town jocks and their bouncy cheerleader girlfriends share a dark secret – and they’re about to share a whole lot more. It’s Halloween, and they’ve got every reason to go wild. Heading out to a remote farmhouse for a night of booze and bad behaviour, they soon find more than they’ve bargained for in the shape of their team mascot, an Indian warrior wielding a lethal fighting axe. One by one they will fall victim to a killer who is about to learn: a dead cheerleader can be pretty… bloody.

Combining archival footage with rotoscopic animation, Tower reveals the action-packed untold stories of the witnesses, heroes and survivors of America’s first mass school shooting, when the worst in one man brought out the best in so many others.
