In a quiet mountain town, good versus evil as the Phantom Force-an army of monsters designed to instill fear-led by the sinister Lord Bane-tries to take over the world and exploit the worst weakness of humanity: fear. Against that, five young brave warriors are chosen to become the Power Rangers Ninja Strike. Equipped with ancient ninja techniques and elemental powers, they battle to protect the world against the Phantom Force. As the battle grows, new allies come to join-with abilities and stories all their own-to make the Ranger team stronger in their fight against darkness.
