The first original drama on PBS in more than 10 years, Mercy Street is set during the beginning of the war. The medical drama's second season will consist of six episodes that follow soldiers at battle, as well as a love triangle among the characters.
Per a PBS press release:
Season two picks up directly from the dramatic events at the end of the season one finale, continuing to explore the growing chaos within Alexandria, the complicated interpersonal dynamics of Dr. Foster, Nurse Mary and the Mansion House staff, the increasingly precarious position of the Green family and the changing predicament of the burgeoning black population. The season will introduce a number of new elements, taking us closer to the fight and into the halls of Confederate power, all set against the intensifying war, starting with the Seven Days' Battle and culminating with Antietam.
