World War I left its impression on many people and many nations. Lives were lost, economies were altered and women's roles were changed as workforces had to adapt. The consequences of international fighting were monumental, but as much as the War set forth great change, it also served as an opening for innovations and new trends. John Carter, unable to physically serve in the war, remains at home in the UK as a temporary head of an industrial company and as the owner of a timber supply business. With men needed at the front, John experiences troubles of a different kind: employing women, searching for qualified help and expanding and converting the industry to suit the demands of war materials. Hunger, illness and heartache strike time and again, but instead of only loss and utmost destruction, The Opportunist shows the tale of one man's success at home in the darkest of times.
