Season 1
A boy is killed and his family embarks on a gangland war with an international cartel: a war that is impossible to win. The Kinsellas are a local crime family, while the Cunningham cartel is a vast global organization. It is David and Goliath. Out-numbered, out-financed and out-gunned, the Kinsellas find themselves holed up in their Dublin stronghold while their businesses fail and family members and associates are picked off. But they have something the cartel does not: the unbreakable bonds of blood and family.

Season 2
The new season will see the Kinsellas at the top of the game in Dublin, but killing Eamon
Cunningham has created as many problems as it solved. They have incurred the wrath of
an enemy even more dangerous than him. And where once there were unbreakable
bonds of blood and family, now there is only suspicion, distrust, and resentment. But the greatest threat to the family emerges from within: in the shape of a ruthless, bullying, agent of chaos. Fortunately, from positions of great adversity the boldest plans are often forged. And so it is with the Kinsellas.
