In the remote archipelago of Tierra del Fuego, Chile, Toto Gesell is living the dream of every 19th-century fortune seeker: he's a gold prospector. Every day, regardless of weather, he dons rubber boots and heads to a creek with a pan, a shovel, and a homemade sluice. Alfredo Pourailly De La Plaza's documentary, shot over nearly a decade, tenderly captures Toto's routine - his wrinkled hands handling tiny gold flecks, his diary entries of hopes and dreams. But his body shows the wear of this simple life.

Enter Jorge, Toto's worried son, who decides to build a trommel from scratch to automate his father's work. This monumental quest takes years, and the film cleverly cuts between the trommel's slow assembly and Toto's declining health. When Toto suffers a serious health crisis while prospecting, time becomes as precious as the gold dust slipping through his fingers. The documentary occasionally zooms out to show the stunning Tierra del Fuego landscape, but ultimately, the trommel symbolizes not just filial devotion, but the love of an entire community. De La Plaza has struck gold - both in subject and execution.
