Soar with the roar of a Samurai Ranger surprise! The Power Rangers continue their fight against evil in all forms, especially their alien nemesis, Lothor. The first attack he launches is a scheme to drain the Power Rangers of all their power. It's all jammin' and no slammin' when Cam must travel in time to snag the ultimate power source - a Samurai amulet that unlocks an ancient mystery. Meanwhile, with things frozen in time, Lothor unleashes Operation Alien Outreach to take advantage of a defenseless Earth. The only hope in the harshness is a surprise Green Ranger with the power to make the thugs disappear.
