Chernobyl was not just the strategic site of the infamous nuclear plant. The towering Duga radar system was also built nearby with the aim of tracking American missile launches. The transmitted radio signal, nicknamed the ‘Russian woodpecker’ due to its characteristic rhythm, jammed Western radio and TV broadcasts. Fodor, an eccentric Ukrainian artist, is the hero of this documentary as he seeks to discover whether the 1986 explosion at the power plant could have been related to this secret antenna. His daring, almost absurd, conspiracy theory helps to reveal the harsh reality of past and present Russo-Ukrainian relations. The film won the award for Best International Documentary at the Sundance Festival.
