A loose adaptation of the first few volumes of the then ongoing Tetsujin 28 manga, the plot involves boy detective Shotaro Kaneda ending up in the control of a 2 meter World War II era robot "Tetsujin 28-go" and with help from the Japanese Self Defense Force and Shikishima Heavy Industries, he must stop the terror group "QX" (PX in the original manga) from using robots to terrorize Japan.—Tokupedia
