Máirín de Búrca has been a tireless social justice activist for women's rights, housing, prisoner rights, anti-apartheid, and many other issues throughout her life.

She has, at times, been a committed member of Sinn Féin and, as a founder of the Women’s Liberation Movement, played a key role in that organisation's infamous Contraceptive Train.

Máirín was also a prime mover in a legal case which secured for women the right to sit on juries, has been jailed for her anti-Vietnam War activities and fined for attacking Richard Nixon’s car during his 1970 Irish visit.

Now, the octogenarian is the subject of a new documentary by filmmaker Cathal Black. A Loner's Instinct traces Máirín's life, taking us from her childhood in Chicago, to her membership of Sinn Féin, to her role as a founder of the Irish Women’s Liberation Movement.

On today's podcast she talks to Kathy Sheridan about her extraordinary life.

A Loner's Instinct will screen at the Irish Film Institute in Dublin April 8th 2019 at 18:30, followed by a Q&A.
