Disabilities:  Cancer

Comments:   In this Greek film a famous writer is dying from cancer. On the street he encounters an eight year old Albanian boy (though of Greek ethnicity) who is running from the police because he is an illegal immigrant. He takes the boy under his wing and the boy gives him some cheer back into his life as he reminisces about his past.
