On the eve of his best friend's wedding, Michael is warned by an old classmate, now a NASA scientist, that a gamma ray burst from a nearby exploding star will hit the Earth the following morning at 11:13 a.m. - an incident that will irrevocably destroy the ozone layer, disrupt the food chain, and ultimately prove cataclysmic for all life on the planet. Michael and the groom-to-be, Drew, laugh off the prediction as a demented joke. However, at precisely 11:13 a.m. the next day, a blinding light in the sky disrupts Drew's wedding. News media outlets dismiss the cosmic event as a harmless phenomenon, but Michael knows better. Wrestling with the burden of his truth, uncertain of how much time he has left or just what to do with it, Michael finds himself alienated from everything and everyone he's ever known. Under Drew's influence, Michael begins to transform his rather mundane life, previously shackled by powerlessness and fear, into something more unrestrained and ultimately dangerous. Feeling the weight of an unseen doomsday clock ticking his final days away, he pushes the moral envelope further and further on a quest for control over his own reality - no matter who might suffer for it.
