A producer at the Belfast bureau of the BBC, Tessa is at work one day when the news of another IRA raid comes on the air. As the anchor requests the public's help in locating those responsible for this latest attack - a robbery at a gas station - Tessa's sister appears on the screen pulling a black mask over her face.

The police believe Marian has joined the IRA, but Tessa knows this is impossible. They were raised to oppose violence and besides, Marian is vacationing by the sea. Tessa just spoke to her yesterday.

When the truth of what has happened to Marian reveals itself, Tessa will be forced to choose: between her ideals and her family.
