Synopsis:
Jimmy Olsen translates a viking tablet and reads it aloud which transports him back into the past. There, he meets Thor and frees the god from imprisonment at the hands of Loki. Jimmy is rewarded by becoming Thor’s pal.

Loki seeks revenge against Jimmy, but Thor rescues his friend when alerted by a horn Jimmy carries. Finally, Loki binds Thor and moves against the unprotected Jimmy. Theorizing that Loki is a 5th dimensional imp like Mxyzptlk, Jimmy tricks Loki into saying his name backwards, transporting him back to his home dimension. Thor is freed, and is able to throw Jimmy back into the present where he belongs.
