[1] With a telefilm format, The Patagonian Bones is based on the true-life story of Catherine Roberts, the first Welsh woman to die in Patagonia in 1865, and on the 20-year work of three Argentine scientists to identify her remains.
Argentine scientists Silvia Dahinten, Julieta Gomez Otero, and Fernando Coronato work for 20 years to determine if the remains found are those of Catherine.
He met Dahinten, Gomez Otero and Coronato who were working on the project as researchers of the National Patagonic Center (CENPAT), a dependency of the CONICET.
When the remains were found in 1995, also recovered were a gold wedding band (with no initials on it), a mother of pearl button, and a coffin made with European wood.
