Adventurer and scientist Andrew Hartford's discovery of the Corona Aurora, a crown that bestows unlimited power upon its possessor, attracts the attention of two warring brothers--the ice creature Flurious and Moltor, a fire demon--who dispatch their hideous minions after its new owner. In response, Hartford assembles a team of five teens from various background (including his own son) and reworks their DNA to transform them into Power Rangers, who seek out the five missing jewels that active the crown's powers.

A team of teenagers with attitude are recruited to save Angel Grove from the evil witch, Rita Repulsa, and later, Lord Zedd, Emperor of all he sees, and their horde of monsters.
