Warsaw, 1981. British academic Joan Andrews (Lesley Manville) is
visiting a Polish university when a violent political protest erupts.
Caught up in the ensuing chaos, she witnesses a brutal murder by the
secret police and captures the evidence on her Polaroid camera. Now
trapped behind the Iron Curtain, Joan is thrust into a deadly game of
espionage involving student rebels and government operatives, where
no one can be trusted and the consequences could spiral into World
War III.
