Goodnight Mister Tom

Tom Oakley (John Thaw) is a cantankerous old man who, at the start of World War II, finds his life irrevocably changed. Without warning, little Willie Beech (Nick Robinson) is evacuated from London and sent to live with Tom in a small village. Willie is a quiet, sad child with a disturbing past, but Tom patiently takes on the job of improving Willie's reading and writing abilities and fosters his natural talent for drawing. Through Tom's friendship and attention, Willie's anxieties are smoothed away and a strong bond develops between this unlikely pair.
However, just as Willie celebrates his tenth birthday, his mother summons him back to the unexpected terrors of Blitz-torn London. Aware of the nightmare that awaits the boy, Tom is forced to act to save the child... and has to fight to keep him. (official distributor synopsis)
