On the streets of Ho Chi Minh City, the destitute children swarm and the rich turn a blind eye. To these needy children "Mama Tina" has become an irrepressible, unorthodox and staunch champion. Within two years of arriving she has opened a Medical and Social Centre and achieved worldwide fame. Bu she berates all those who call her a "Mother Teresa". In her own words she is "one street child using her wiles to help other street children". Christina's story is punctuated by flashes of humour and exurberance that are both her trademark and her means of survival.
