The outskirts of Yerevan, the capital of Armenia, are bleak.  While 12 year-old Arthur is proud of his birthplace and home, he has also witnessed the elimination of almost all of Yerevan’s trees for firewood during an energy crisis.  Developers have decided to build a garage on his deserted and dusty school playground where only one poor, semi-withered tree survives.  Arthur is determined to save the tree and build a real garden with the help of this ecologist grandfather, schoolmates and teachers.
