Eleven years have gone by since Tom-Tom rescued his girlfriend Tanya from the clutches of the evil King. Word of Tom-Tom's dangerous adventure soon spread throughout Wonder Land. The people were very proud of Tom-Tom and gave him the highest honor of all — the legendary name of Wonder Boy. With the evil King defeated, Wonder Land returned to its peaceful state, and for over a decade, the kingdom was a paradise, and everything and everyone lived happily together.
Eventually, the peace was broken when a ferocious fire-breathing dragon appeared out of nowhere and took over Wonder Land with an army of evil, monsterous henchmen, throwing Wonder Land immediately into utter chaos. The defenseless people were quickly taken over and the tranquil and serene kingdom was transformed into a land of demons and devils. Wonder Land was now a Monster Land. Tom-Tom, Wonder Land's last hope, is now summoned to set out on a journey, destroy this dragon, and restore peace once again.
In this movie, Dadoc guides Tom-Tom through this journey, utilizing luck manipulation and a glitch allowing him to pass through the floor to defeat the dragon and save Wonder Land in just over 11 minutes.
