In 2008, construction workers just beyond York's city walls uncovered 113 bodies in a mass grave. The History Cold Case team spots an incredibly rare genetic peculiarity in two of the skeletons among the 113 and wonder whether they have stumbled on a pair of brothers, one of whom was severely disabled. The trail to find out who these two men could have been and how they ended up dead in a mass grave outside York opens up a new personalised vantage point on the events surrounding the English Civil War and also gives us a perspective on disability which can perhaps teach us something about so-called modern attitudes today.
