Resistance

At the height of the War of Independence, Michael Collins’ squad member Jimmy Mahon is given an intelligence role while Ursula Sweeney, a code-breaker with British intelligence at Dublin Castle, contemplates treason.

Jimmy breaks Joey out of prison, and helps Ursula to be reunited with her son. Eithnes outrage at Diarmuids death is ignored, and Maurice faces an impossible choice.

In the aftermath of the multiple attacks on General Winter’s spy ring, the British close ranks. There’s a price on Ursula’s head and Jimmy finally confronts the mole inside Collins’ Squad. General Winter commissions Major Mills to take men to Croke Park.
