Stand Clear of the Closing Doors

The story of Ricky, a 13-year-old boy with autism, and his mother, Mariana, an undocumented immigrant from Mexico, who works long days cleaning houses while Ricky, deeply imaginative but painfully isolated, struggles to cope. One day nobody picks Ricky up from school and he begins an odyssey of self discovery,
where his confrontation with the bizarre, indifferent world of the subway pushes him
to interact with the world.
