On what should be one of the happiest days of her life, high school senior Wendy (Mary Elizabeth Winstead) joins her friends for a graduation night celebration at a local amusement park. Secured in her seat on a roller coaster, Wendy experiences a vivid premonition of a fatal accident in which the roller coaster becomes a death trap for her and her friends. Emerging from her terrifying vision and still on the ride platform, Wendy demands to be let out of the coaster car. When a fight breaks out, a handful of students are forcibly ejected from the ride. As they watch their classmates and friends from the ground below, Wendy’s premonition proves nightmarishly true--the coaster careens out of control, and all of those aboard perish. But that's only the beginning. Those who survive the disaster discover that fate is hard to escape. They were meant to die--and death is not so easily cheated! It's not long before death comes to claim its next victim, and it's through this tragedy that Wendy realizes that there are clues to the survivors' impending demise contained in photos she took at the amusement park that fateful night. As Wendy and her classmate Kevin (Ryan Merriman) desperately try to interpret the clues that might save lives, one-by-one their friends meet fantastically gruesome ends....and soon it will be their turn.
