It was an adaptation of the Japanese tokusatsu series Gridman the Hyper Agent.

"The evil Kilokahn lives inside computer circuits! With the help of Malcolm Frink, he creates Mega-Virus Monsters to attack electronic systems! Meanwhile, a freak accident turns Sam Collins into Servo. His friends join forces in their samurized attack vehicles. Together, they transform into...the Superhuman Samurai Syber-Squad!"

High school student Sam Collins, the head of a band known as Team Samurai, is zapped during a recording session by a power surge and disappears, only to return seconds later with a strange device attached to his wrist which, at the time, is unremovable.

Later after his friends, Amp, Sydney, and Tanker leave, one of his video game programs, dubbed Servo, is subject to a power surge and zaps Sam again just after he has remarked "Cool battle armor!" - this time he is pulled into the digital world and transformed into his creation. As Servo, he roams the digital world and fights monsters dubbed Mega-Viruses which are capable of attacking any device on the electrical grid (including the grid itself), Internet or telephone network, usually having real-life consequences far beyond what any standard computer virus would be capable of achieving.

Meanwhile, Malcolm Frink, another student from Sam's school, is designing monsters on his home computer when Kilokahn, an escaped military artificial-intelligence program that was presumed destroyed in the power surge, visits him via his computer screen and strikes a Faustian deal with him, transforming his digital monster into a Mega-Virus.

Sam, now as Servo, must enter the digital world and stop Malcolm's and Kilokahn's Mega-Viruses. Sometimes, when Servo is unable to handle a virus by himself, he would enlist the help of his friends using his Arsenal Programs which could fight the viruses solo, transform, with the help of other Programs, and attach to Servo as armor. Since Team Samurai consists of only three people at any one time following Sam's disappearance, only three vehicles are available for use at any one time. When Servo combines with these Programs as armor, he changes his name to either Phormo once combined with Drago or Synchro once combined with Zenon.

The Mega-Virus Monsters are Kaiju-style computer viruses produced by Malcolm and given sentience by Kilokahn. Malcolm creates the Mega-Viruses since Kilokahn lacks the ability. Only a few Mega-Viruses have the power of speech.

In an odd occurrence, Zenon fights Servo in "Que Sera Servo" when a Mega-Virus places Servo under a spell which has him obey solely Kilokahn, until Amp is able to break the virus' hold by using Syd's belt to reboot him.
