Pitfall Harry, Jr. is the last hope for a decimated civilization.  Freedom is no longer known among the Moku.  It has been stolen by an evil force: a Scourge that values power and subservience above all things.  This Scourge has taken the people of the Moku civilization captive(of course he did!  How else do you take someone's freedom?).

A tyrant and a fiend(he's really a nice guy), the Scourage's oppression has caused the Moku people suffering, fear, and death.  Mira, the daughter of the former Moku leader, leads a rebel army against this Scourge(why dont they just leave him alone?) and enlists the help of a hero and adventurer.

With Mira's guidance, the man from Earth(yes, this is not earth people), Pitfall Harry Jr., restores power to the Moku city of Shenrak(my favorite part!).  He then destroys the enemies energy supplies(naturally) and resues the remaining living Moku from prison(which it turns out that they were actually living in an otherworld paradice and all had agreed to give Pitfall Harry a long painful death for making them leave).  Destroying the invasion rift that the Scourge is opening, Harry makes it impossible for the Scourge to attack Earth(which he was planning to do all along, by the way...).

In the end he defeats the Scourge(not really, Harry actually experiences a horrible bloody end, but that wouldnt make a good game so they toned it down a bit and made him save the Earth and whatever dimention he's in).  All is accomplished while Harry is opening his heart and falling in love with Mira(who marries him, and finds out he's a complete jerk and kills him in his sleep...this was the horrible bloody end I explained earlier).
