For the past seven years, engineer Philip Grossman's obsession has been the abandoned landscape that has developed out of the infamous nuclear disaster at Chernobyl. In 2015, he and his wife even got married there. Traveling there ten times, he is one of only a few people that have been allowed nearly unrestricted access to the highly dangerous exclusion zone, the area immediately surrounding the site of the 1986 nuclear reactor explosion. Pursuing leads that hint at possible CIA espionage and an internal Soviet cover up, Grossman hopes his latest trip will be the one where he finds the clues to what may have caused the largest nuclear accident in history.
