Hangman's Graveyard follows a team of archaeologists as they unearth a forgotten graveyard behind the infamous Old Don Jail in downtown Toronto.

Buried beneath what is now a parking lot are the skeletal remains of 15 men who went to the gallows between 1880 and 1932.

Who were these men? What were their crimes? And how did they spend their final moments as they awaited the end of the hangman's noose.
