Season three of Brotherhood® continues the blue-collar saga of Providence, Rhode Island native sons Michael and Tommy Caffee. After winning his closely contested re-election campaign, Tommy is left as a subordinate to Speaker Donatello, which makes him contemplate leaving political life altogether. But, to do that, he needs to make some money first. And how do you make money as a politician? You play fast and loose with the rules. To wit, Tommy takes an under-the-table piece of a large-scale construction project. As for Michael Caffee, his precarious position as boss comes under siege as he is slowly overwhelmed by ever-building paranoia. While Michael is obsessed with his business foes, it is his personal life that poses the greatest threat as his cousin Colin finds himself attracted to Michael's common-law wife Kath. The rest of the Caffee family returns for season three - Tommy’s wife Eileen and his mother Rose, along with local cop and Caffee family friend Declan Giggs and crime boss Freddie Cork.
