A Right Rose Tree

S1, E5: Sweeney allows Roarke to sell cocaine, but only if he bankrolls and sources it alone. That puts Roarke in Gotti's crosshairs, as Gotti grows suspicious that the Westies are defying Castellano by moving cocaine on their own. They must sidestep Gotti's push to supply them. Meanwhile, Bridget helps Cahill secure new explosives for their IRA plot, and Polk pressures Keenan to wear a wire to dig up dirt on Sweeney's crew.
