Infuriated by T-Rex's triumphs and his own thugs failures, Boss Graves imports an out-of-town hit-dino - an enormous, fire spewing, Godzilla like monster, named Hot Shot, to eliminate T-Rex from Rep City.

Boss Graves has his eye on a priceless Soap Diamond, but Shooter, his chief hench-reptile, is too busy falling in love to have his eye on anything but the dino-lady concerned.

After T-Rex foil him yet again, Boss Graves and Shooter hatch a clever scheme which involves the famous film director, Percy B. DeMillions offering Bruno and Bernie roles as robbers in a new movie, ""The Bank Heist"".

The new Rep City gymnasium becomes the scene of Boss Graves' latest scheme when the Black Widow - an aerobics instructor - hypnotizes Mayor Maynot into disrupting the political structure of the city.

After T-Rex stop the Corporation boys from robbing an armored car, Boss Graves orders his men to expose the real identities of T-Rex and ""ice 'em"".
