Mags Duffy, lone wolf and union woman through and through, left a boring union conference as two days of Irish icy-snow had brought town to a halt. Freezing! Worst cold spell in a generation. Night Creatures focuses on a taxi driver on New Year’s Eve in Dublin. Not many on the slushy roads. Roving cab-seekers flock and mob the streets. You have to stand your ground. Coffee and Star Bars would keep Mags going.
