When Louise Quill was 22, she did what a lot of young people do and went on a volunteering mission to Kilimanjaro in Tanzania.

Dismayed by what she found there, Louise put her heart and soul into building one of her own.  In 2006, she established the Tir na nÓG orphanage which is now a home and a family to children from the area.

Known to the children as 'Big Mama', Louise's incredible story of overcoming what often seemed like insurmountable personal and professional hurdles has been transformed into a new documentary.

Louise joined Dermot and Dave to chat about the inspiration behind establishing Tir Na nÓg and why the love she has for her children keeps her going, even at the lowest points.
