In January 1972, during General Lanusse's dictatorship in Argentina, a group of revolutionary activists occupied the National Development Bank, just meters from the Government House, expropriating 450 million pesos (approximately 10 million dollars today) for their cause. This was made possible by Oscar Serrano and Ángel Abus—activists and bank employees—who spent two years preparing what would become the biggest blow to the dictatorship's finances. Forty years later, Oscar and Ángel, along with a group of actors, recreate those events that changed their lives. In this dialogue between generations, the young people transform their perspective on activism and commitment during those years. Narrated through several cinematic layers, Seré Millones (I Will Be Millions) offers an innovative story that blends humor, rigorous historical research, and the epic spirit of the era.
