The year is 1973. Life is normal on the Island of Sodor. Contracts were being made, and buildings being built. A nuclear power-plant on the Brendam had been built, but after that... all hell broke loose.

Years of poor maintenance and filthy work conditions, the Sodor ironworks begins to leak a poisonous liquid. The rest is chaos.
