'The Carrier' is a feature-length documentary that tells the inspiring story of an HIV-positive and pregnant mother trying to protect her baby from being born with HIV/AIDS. The film follows a Zambian subsistence farmer named Mutinta who is part of a polygamous marriage where everyone is HIV-positive. With the dangerously high mortality rates for HIV-positive babies on her mind, Mutinta enrolls in an innovative public health program called Prevention of Mother to Child Transmission (PMTCT).
