As the morality police crowded around her table in a Khartoum restaurant, leering at her to see what she was wearing, Lubna Hussein had no idea she was about to become the best-known woman in Sudan. She had arrived at the Kawkab Elsharq Hall on a Friday night to book a cousin's wedding party, and while she waited she watched an Egyptian singer and sipped a coke.
She left less than an hour later under arrest as a "trouser girl" - humiliated in front of hundreds of people, then beaten around the head in a police van before being hauled before a court to face a likely sentence of 40 lashes for the "sin" of not wearing traditional Islamic dress.
The officials who tried to humiliate her expected her to beg for mercy, as most of their victims do.
Instead she turned the tables on them - and in court on Tuesday Mrs Hussein will dare judges to have her flogged, as she makes a brave stand for women's rights in one of Africa's most conservative nations.
