When high school student Ryan Walker discovers he has the ability to control technology with his mind, he awakens 150-foot robot MECH-X4 and is able to control every move the android makes. The situation gets to be too much for Ryan to handle on his own, though, when another monster starts attacking the school. That's when Ryan recruits older brother Mark and friends Harris and Spyder to help operate MECH-X4's defence system while he pilots the robot. Together, the haphazardly assembled team of heroes must quickly learn to work together in order to save the school - and, ultimately, the world - from being destroyed. That's a lot of pressure to put on some teenagers.
