It’s 1981 and Belfast is burning. So, too, is freshly widowed Bessie Halstone: she burns with a desire to break with her troubled past. With her feckless husband gone, she leaves home hurriedly with her naughty nine-year-old son, Herkie, and not much else. But an IRA enforcer is on her tail. He’s convinced that Bessie, with her “yella hair all puffed up like Merlin Monroe’s,” has absconded with the takings from a bank heist.
