The episode starts with a battle between Servo and a virus, he calls for help and Sydney queues up the Jamb and Torb program so she and Tanker can assist, Amp is upset that he can't join in but Sydney says that he has to monitor them. They port in and help defeat the virus, after they come back they head to school or they would be late for their report card day. Sydney loves report card day because she always Aces her reports.
The boys are generally happy with their report cards, but Sydney is upset because she got a 'B' in one of her classes which delivers a blow to her self esteem. In her departure she runs into Malcolm and just walks off, Malcolm decides to use this as an opportunity to really make Sydney lose control of her life, and resurrects Skorn, sending him into Sydney's digital wristwatch. Her hand soon develops a life of its own, performing complicated and sometimes impossible tasks, like tying Amp's shoes together or stealing Sam's wallet without her or them noticing. After a while the petty thefts around the school culminate in finding the stolen equipment stuffed in her locker. Principal Pratchert is ready to punish Sydney, but Tanker takes the blame.
After Sydney unconsciously punches Tanker out, Sam tries to get Sydney to admit she has a problem and Skorn makes his presence known. Sam goes into the computer as Servo to stop Skorn while Amp and Tanker struggle with Sydney's hand which tries to interfere with their assistance. Just as Sam seems doomed to be destroyed, Sydney forms a weapon combining his samurai sword with his shield, turning it into an axe, which he uses to quickly dispatch Skorn. Sydney's hand returns under her control and everything seems to have returned to normal.
