A seasoned financial professional, "De Wiel" (played by Fabrizio Rongione), travels from Geneva to Buenos Aires in the 1980s to replace a colleague who disappeared under strange circumstances. The setting is significant because at that time, Buenos Aires was still governed by a military junta and the Catholic church. There were widespread stories about his predecessor’s involvement in questionable financial matters, so De Wiel's mission involves not only satisfying clients but also uncovering what happened to "Kies." He soon finds himself immersed in pervasive corruption affecting nearly every aspect of society; his task is to generate profits for those he works with – without regard for ethical considerations or potential dangers – and to do so with utmost secrecy. I felt the film could have benefited from a quicker tempo, but director Andreas Fontana delivers a powerfully portrayed look at how deeply corrupt and threatening conditions were. Those around him, sensing that their situation might be precarious, frantically attempt to sell off assets—assets which may or may not have belonged to them—in order to safeguard themselves in another country. His interactions aren't limited to the wealthy elite; he confronts people from all walks of life within a community that had long accepted ignoring problems or passively participating in wrongdoing. The cinematography complements the sparse dialogue, and it’s a rather successful psychological thriller that requires viewers to actively interpret events and form their own conclusions.
