The year 2067 after much of the world has been obliterated in a nuclear holocaust. Seattle and Lancer are two rebels fighting against the dictatorial Cabal that has taken over the ruins of the world. They make it to a rebel stronghold where they agree to send their minds back in time to 2017 in hope of preventing the war. In present-day Arizona, teenager Ava sneaks out from home to a party but collapses in the middle of it. After coming around some hours later, she makes her way home – only to find another version of herself asleep in bed. She makes the realisation that she is now disembodied, unable to be seen by or talk to anybody. Her body has been taken over by Seattle who now sets about reuniting with Lancer and her rebel cell in this time. Meanwhile, The Cabal is tracking their whereabouts and sends The Huntress back in time to stop them by driving the rebels out of their hosts, while their original bodies are destroyed in the future, leaving them disembodied. Throughout all of this, Ava tries to find a way to get her body back, even as she realises that she is meant to have died at the party.
