Bird Box jumps between two timelines – we start with Malorie (Sandra Bullock) and two kids travelling blindfolded in a boat down a river, where to we do not know, but right from the opening scene learn that they must not look or they will die. The second timeline is about 5 years earlier where we meet a then heavily pregnant Malorie and her sister Jessica (Sarah Paulson), as they see news reports about some unexplained phenomenon in Europe and Russia causing mass suicides.
This movie tells the story of Rex (Michael Caton), a taxi driver who has never even left his hometown of Broken Hill, NSW. Just as Rex learns his stomach cancer has spread and the doctors give him maximum three months to live, he hears the news that voluntary euthanasia has been legalised in the Nothern Territory. Within a couple of days he is on his way in his cab to Darwin to find Dr. Farmer (Jacki Weaver), who is in the limelight for championing a new euthanasia programme.
