Lessons from the night --"This innovative documentary follows Maia, who reflects on life, work and toilet bowls on her nightly cleaning rounds through silent, empty spaces. As she works, she reveals some of the secrets of the city - the traces of human presence that we leave behind each day - and of her former life in Bulgaria." -- Container. "Karen has left her slimy but successful husband Mario after ten years of marriage. She needs a fresh start to find out who she is and who she could be, despite her husband's proclamation that she can do absolutely nothing. She walks out into Bogotá with no job, no friends, and hardly any money, but catches a break when she meets a hairdresser named Patricia at a cheap flophouse. With her younger and seemingly stronger friend by her side, Karen takes her first steps towards independence and self-discovery." -- Container.
