The battle starts during the Spanish era when Apo Abukay (Gardo Versoza) wants to gain power as he plans to dominate the world. He then failed to fulfill his plans after Conde Vergonze killed him. After his death, his cursed soul remains. Many years later, during the 1980s, Karag-ayan Amelia (Lorna Tolentino) and the Binhi-lan Rodolfo (Jestoni Alarcon) fall in love with each other. Amelia gives birth to twin boys. The two are raised separately, not knowing that the other exists. Miguel (the son of light) is kind, good-hearted and lives a modest life; the other, Amante (the seed of darkness) is raised with hate and rage, but with riches and power.
