Blood Feuds.

American Heroes Channel presents epic battles between strong-willed contenders convinced of the righteousness of their sides with the outcomes determined in blood. Using dramatizations, interviews, and stylized storytelling, six hourlong episodes bring to life true stories that defined American history's most notorious feuds and rivalries, from racist street gangs battling for territory to former friends turned mortal enemies. Among the featured combatants are the Hatfield and McCoy families, Old West crime boss Jefferson "Soapy" Smith, and Bowery Boys' leader William "The Butcher" Poole.
