To correct the Swellview clock tower, the city cuts power for ten seconds. That frees Drex from confinement in the Man Cave storage room. Using the Time Jerker's time portal, he quickly flees into the past with Ray and Henry hot on his heels. They all land in April 27,1989 -- the day Ray became indestructible. Meanwhile, as Ray and Henry seek help from teenage Schwoz in college, Jasper, Charlotte and older Schwoz seek Piper's banned Gloey Zoey doll for its radioactive content to fix the time portal that Drex sabotaged.
