Bad Blood is a Canadian crime drama television series created and produced by Simon Barry. The show premiered on Citytv on September 21, 2017. A French-language version of the show premiered on November 11, 2017 on Ici Radio-Canada Télé under the title Les liens du sang. It was initially intended as a miniseries; however, it was renewed by Rogers Media for a second season in March 2018, which was broadcast on Citytv and FX Canada. The first season is a dramatization of the rise and fall of the real-life Rizzuto crime family, a Montreal-based organized crime family, and is based on the 2015 book Business or Blood: Mafia Boss Vito Rizzuto's Last War by Antonio Nicaso and Peter Edwards. The second season departs from the book and is fully fictional.
Set in Montreal between the early 2000s and early 2010s, Vito Rizzuto, the boss of the real-life Rizzuto crime family, seeks to bring peace to the criminal world in the city. However, when Vito is implicated and arrested for multiple murders committed in 1981, he puts his right-hand man, Declan Gardiner, in charge, and his empire begins to crumble. Upon Vito's release, he sets out on a path of revenge. Declan eventually finds himself at odds with new rivals, twins of a head mobster from Calabria, Italy, Teresa and Christian Langana, who are related to the Cosoleto brothers in Hamilton.
