It's 1976 again. Abba are on the charts, the Cold War is in full swing -- and the Earth is flat. It's been flat ever since the eve of the Cuban war of 1962; and the constellations overhead are all wrong.

Gregor, in Washington DC, knows but isn't talking. Colonel-General Gagarin, on a years-long mission to go where New Soviet Man has not gone before, is going to find out.
