From the writer Tom Bradby and director James Marsh comes a pretty tense drama thriller called Shadow Dancer. The stroy begins in 1973, when a young girl, called Collette (Maria Laird) gets a task from her father to go and run an errand, but since she is in the middle of her necklace making and her interest in that is far greater, she sends off her younger brother Sean (Ben Smyth) and he gets killed right in front of their home. 20 years after that event, Collette (Andrea Riseborough) is a mother who needs to take care of her son and is working as a mole for the IRA. After doing what she is told to and leaving a bomb in that facility, Collette gets arrested. While it seems like she's going nowhere, an MI5 Agent Mac (Clive Owen) shows up interested in her case and gives her an offer which she simply can not refuse. The deal is to become informer for MI5, with certain conditions. One of which is, when she's done, she gets a new identity. Other one is to have her son safe at all the times. Not long after everything starts developing its own way, Agent Mac reveals that one of his superiors Kate Fletcher (Gillian Anderson) is protecting one of the moles in the Irish organisation by putting Collette and her life in risk, and he is trying to do everything to have Collette safe and sound. Along the way, we see how Collette's family gets targeted by both sides she works and had worked for. The end only reveals who this true informer is and was it all worth it.
