Angeline Murphy - 'Angel to her friends, devil to her enemies' - is a feisty wee Belfast girl who works for the local BBC.

She meets a young Polish girl - Elena - near the City Hall. Elena desperately needs help - she has been enticed over from Poland by the promise of a job, to find herself, instead, being used by people traffickers.

Angel is angry and horrified to find this happening in her home town. Determined to put a stop to it, she is soon on a trail which takes her to the city of Krakow, Poland - together with Elena's friend Magda.

There she meets up again with her friend Josh Smith - of Interpol - and between them, after hair's breadth escapes, rescues, and thrills - amid the falling snow - they track down the boss of the people trafficking gang, and bring about a happy ending - in more senses than one!
