Shin Mi-sik, a Korean documentary photographer who loves Madagascar, built four libraries for children in Africa. In order to protect children's innocence and artistry, this time he want to convey music. With 50 ukuleles supported by a Korean cultural foundation, he leaves for Madagascar with composer Taehwa Jang and 14 volunteers. Although they are poor, they live with a positive outlook on life. The children, who find everything amazing, are absorbed in ukulele lessons and choir practice despite the hot weather. The beautiful performances and singing of a 50-member ukulele troupe and a 100-member choir resonate movingly at Trinity School, the beach, and Baobab Street in Morondava, Madagascar. Through the process of preparing for a ukulele performance with Madagascar children, we encounter the simple truth that the most beautiful gift to us is ‘music.’
