Paraguay, 1958. The charismatic Narciso returns from Buenos Aires with rock ’n’ roll in his veins. Under the suffocating military regime, his radio show becomes a music sensation and a symbol of freedom.

Los Buscadores tells the story of Manu, a young paperboy who lives in the Chacarita neighborhood. He receives an old map, a gift from his grandfather, and embarks on the adventure of finding a treasure called "Plata Yvyguy", gold and jewels buried by families in Paraguay's 1864-70 War of the Triple Alianza.
