From The Jacket:
The Rent Collector is the story of a young mother, Sang Ly, struggling to survive by picking through garbage in Cambodia's largest municipal dump. Under threat of eviction by an embittered old drunk who is charged with collecting rents from the poor of Stung Meanchey, Sang Ly embarks on a desperate journey to save her ailing son from a life of ignorance and poverty. It's a tale of discovery and redemption in which she learns that literature, like hope, is found in the most unexpected places.
