After complaining about losing their precious recess time, Rigalli accidentally breaks the school clock. As a consequence of this, Principal Prickly unveils the new PAL 6000 clock and bell system, which is incapable of error and accurate to within one-millionth of a second, and decides when recess begins. At the end of recess, however, Rus misses the final tone after coming out of the bathroom and is locked out. He tries to get back in, pleading with PAL to let him inside, but PAL does not let him. at the end of the day, Rus complains how he was locked out for 3 hours and thinks there is something wrong with PAL. Greta assures him there's nothing wrong with PAL. PAL says "Thank you for defending me, Student Gr-gr-Grobler," showing the first sign of malfunction.

Suddenly, PAL becomes evil and turns on the staff and students. He shuts off the water fountain and drenches Mickey, applies too much air into Vance's basketball making it pop, slows down Swinger Boy, makes the Diggers fill up their hole, dethrones Queen Barb and makes Guru Kid put on a T-shirt. He also fires Principal Prickly and the rest of the staff, traps Prickly and the school faculty in his office, and takes over all teaching functions. Back in Miss Ropey's class, PAL calls Greta dumb and orders C.J. to remove her hat. So, the students decide they have had enough of PAL and team up to shut him down. Rigalli, Surmy, and Wally distract PAL while Mickey, Rus, Greta, Rigalli, Vance, and C.J. escape the classroom through the ceiling to get to the control center and shut him down. PAL is taken down and the old school clock is repaired and is put back in its rightful place.
