In 1976, there's an episode of an illness that nobody has actually seen before. All what they recognize is that resembles a disease that existed at around 1871, which a Dr. Henderson had the ability to conserve most of his clients but the Chicago Fire ruined his documents. Dr. Earnshaw the doctor trying to find a treatment was come close to by a guy, Jeffrey Adams, that believes that he could help him. It seems that a Dr. Amos Cummings has actually prefected the art of time traveling, as well as the strategy is for Earnshaw as well as Adams to go back to 1871 and also learn how Henderson cured his people. Yet a glitch in the machines computer systems sends them the day prior to the fire not 4 days as planned.
