What is "pumzi"

Pumzi is a Kenyan science-fiction short film written and directed by Wanuri Kahiu. It was screened at the 2010 Sundance Film Festival as part of its New African Cinema program. The project was funded with grants from the Changamoto arts fund, as well as from the Goethe Institut and Focus Features' Africa First short film program which are also to distribute the work. Kahiu hopes to expand the short into a full-length feature. The film is in English, but the title is Swahili for "Breath".
