Haru Irei is een jonge jongen die fan is van de Gundam-saga; hij raakt dus in de ban van de robotmodellen van de franchise, maar vindt in de winkel alleen een onbekende robot, de Beginning Gundam, die hij samen met zijn vriend Kenta Sakazaki in elkaar zet. Deze laatste neemt hem vervolgens mee naar een Gunpla-toernooi, waarbij de deelnemers strijden via een gevechtssimulator waarmee ze virtueel de controle over hun model kunnen overnemen in een 3D-omgeving.
Nee, helaas is 模型戦士 ガンプラ ビルダーズ ビギニングG nog niet beschikbaar op Netflix in Nederland.
