Ten-year-old Moises has just immigrated to California from Mexico. He doesn't speak English, but he's good at math, so he hopes to do well on his first math test in the USA. Using untrained child actors from public schools in the San Francisco Bay Area, “Immersion” plunges its audience into the visceral experience of a child who cannot understand his teacher. The film puts a human face on the debate about the education of English Language Learners.
