Two men while away the days in an Antarctic research station. Tensions between them build as they argue over a love letter one of them has received. One is practical and open. The other surly, superior and obsessed with reading one book - by the philosopher Kant. As a storm brews and they lose contact with the outside world they debate Kant, reality and the emptiness of the universe. The come to hate each other - and they learn that they are not alone.
