In a not-so-distant future, Earth has been placed on high alert after astronomers warn of an impending catastrophe. A massive comet, categorised as a Planet-Killer, is swiftly hurtling towards our home planet, with a relentless trajectory that won't allow for any timely course correction. News of the impending doom spreads like wildfire, sending panic and chaos throughout the globe as governments struggle to find a way to mitigate the disaster. For John Garrity, a former Special Forces operative turned rescue pilot, the news is nothing new. Having lost his initial job, John works for the Civil Defence. In an attempt to soothe his own fears of inescapable apocalypse, he drives home with his young son Nathan, thinking this will be a relatively safe place for them to cope with the uncertain future ahead. However, fate is cruel and has its other plans laid out for John's small family. He immediately asks Nathan's mother, Kate, his estranged wife, to pack an essential list of belongings and the couple's car since John has chosen a destination, up north. The plan, however imperfect, was to reach John's sister, Krista, a health care worker, in Greenland. Why Greenland? According to her intel which is constantly getting revamped, a US Air Force base in Greenland was listed to be prepared for an 'event', presumably of a catastrophically apocalyptic nature. Throughout the first part of the grueling drive, the couple barely gets out the strained relationship with an innocent kid locked in the middle. They periodically end up arguing, mostly sparked off by Kate’s displeasure about how they should plan forward if, albeit highly speculative, this sort of apocalyptic event happens. They encounter a number of threats during their journey as panic grows, but this time a mix of desperation is in play that seems to nudge them face-to-face with both the most evil and beautiful sides of humanity. Subsequently, they're stopped at a heavily-congested police check-post. As it gets imperative that they not get late for their final shot at survival, a visibly-tired John somehow manages to convince his fellow countrymen to keep them prioritized in order to navigate, allowing their critical lifeline - getting to the supposedly safe location in the isolated region of Greenland to start. Taking a sharp right there, John picks up speed and drives; attempting by far every possible safety measure along the way through increasing chaos - giving it everything. But John encounters some other crisis; witnessing extreme depravity on the road – and Kate realises all that really counts is family. Here, surprisingly, we witness one of the best in human generosity as strangers end up rescuing the driver and daughter. Despite living by the utmost brutality and cruel motives in the days of pandemonium - miraculously even at an end point near his family - man stands up brave. The movie finally takes off with their journey's crescendo. By speeding through, with everything on the highway on fire and desperate for safety in Greenland- everything sets in order- even if somewhat unexpected-and heartwarming. Hence a mother taking step after taking another back to her estranged husband's desperate attempts coupled up their uneventful progress as everyone tends to be together during shared terrifying last moments. On the eve of its apocalyptic end, John makes the most of them - taking himself in control of the steering and puts his skills to a relentless test yet. With everything put into play amidst roaring destruction, every shred of common sense, optimism and humanity found in this family suddenly appears. As if there actually was a world that still thrived so as to be forever etched into that great final day.
