During the bus ride to a corporate retreat, Sam (Nicholas D&rsquo;Agosto) has a premonition in which he and most of his friends &mdash; as well as numerous others &mdash; die in a horrific bridge collapse. When his vision ends, events begin to mirror what he had seen, and he frantically ushers as many of his colleagues &mdash; including his friend, Peter (Miles Fisher), and girlfriend, Molly (Emma Bell) &mdash; away from the disaster before Death can claim them. But these unsuspecting souls were never supposed to survive, and in a terrifying race against time, the ill-fated group tries to discover a way to escape Death&rsquo;s sinister agenda.</p> </p>
