The moving story of Mission Choir, which brings love and emotion to many people through song. Mission Choir visits Cambodia for the Cambodian children who are losing their dreams and hope due to a difficult life. Initially, outsiders were seen as a nuisance by the local Cambodians, who had no time to pay attention to their children due to financial difficulties. However, many Mission Choir members sing with their hearts to sincerely approach the Cambodians, gradually healing their wounded hearts and slowly opening the doors of their minds. Young children were initially hesitant towards people with different appearances, but upon hearing the songs of Mission Choir, they felt love and attention, and small changes began to occur in their lives.
