1941: sisters Thom and Mars have built a machine, LOLA, that can intercept radio and TV broadcasts from the future. This allows them to listen to iconic music before it has been made, place bets knowing what the outcome will be and embrace their inner punk well before the movement came into existence. But with the Second World War escalating, the sisters decide to use the machine for good to intercept information from the future that could help with military intelligence. The machine initially proves to be a huge success, rapidly twisting the fortunes of the war against the Nazis. While Thom becomes intoxicated by LOLA, Mars begins to realise the terrible consequences of its power.
