2067, Earth is on the verge of collapse. After years of doing too little to reverse climate change, plant life is extinct and there is a dramatic reduction in available oxygen. The survival of humanity is threatened by a fatal “oxygen sickness” – as manufactured oxygen, the only source of breathable air, is making millions sick. With no cure in sight, humanity looks to the future, in the hope that people are still alive and have a solution to the O2 crisis. Chronicorp, the world’s leading supplier of synthetic oxygen, has spearheaded this project, building a quantum time machine that pings the future in search of a connection with their descendants. They receive a response: a message from 400 years in the future that simply reads “Send Ethan Whyte”. Unwittingly, Ethan, a reclusive utility worker, barrels into the future as humanity and his sick wife’s last hope. He arrives in a new world... completely alone. As he draws closer to the truth and uncovers an unthinkable conspiracy, he is faced with the ultimate question - who sent the message? And is there a way to save humanity and the woman he loves?
