In the near future, humankind has been almost wiped out by Covid-19, and the bourgeois class (people of the future) build huge walls to stop the spread of the coronavirus and live in the artificial utopia ‘Inner Wall’. In the world on the other side or ‘Outer Wall’, proletarians (people of the past) live in poor conditions. A disillusioned dancer in Inner Wall named Ee Ah stumbles upon an old book about ‘geomagnetic reversal’. Ee Ah plans to send a signal to outer space in time for the Earth’s reverse polarity, which appears once every 200,000 years. Then Ee Ah goes to the North Pole, where the magnetic field is the strongest on Earth.
