Darna at Ding (1980)

Narda (Vilma Santos) receives superhuman powers and becomes Darna. Darna and her younger brother Ding (Niño Muhlach) start by fighting the Hawk Woman; next they face off with the Giant, and both foes are destroyed. They meet Dr. Vontesberg (Marissa Delgado) a good-Samaritan doctor who secretly plans to destroy an entire village to avenge her grandfather, who had been mistakenly accused of being a devil worshiper. Dr. Vontesberg also has powers to summon the dead and terrorize the townspeople. Narda is captured by the evil doctor, who shows Darna how she intends to achieve her plan. Just in time, Ding arrives to rescue his helpless sister and together they stop Vontesberg's plan. Then, Darna and Ding make their way to the city, but they are captured by a Sorceress, and join a bunch of other prisoners. Sorceress Lei Ming (Celia Rodriguez) and Darna measure their strength and powers. Lei Ming creates a clone of Darna to destroy the real Darna. The real and the cloned Darna fight hand-to-hand, and the good Darna proves to be the stronger. After losing face, Lei Ming takes her own life.
