Last modified on Wed 12 May 2021 07.34 EDT S et in the late 1950s in a geographically vague American suburban town where fin-tailed cars roll sedately through the streets and women wear dresses shaped like great silent bells, local doctor Lewis (Chris Messina) and his Romanian-born wife Maja (Noomi Rapace) and their grade-school son Patrick (Jackson Dean Vincent) look like everyone else pursuing the American dream. But as the title rather suggests, there are secrets afoot; quite a few in fact. They all start to come out when Maja spots a tall blond man (Joel Kinnaman, in fact, and, like Rapace, originally from Sweden) with just the faintest German accent. Maja is completely convinced this European, who says heâs a Swiss national named Thomas, is really a German named Carl who did unspeakable things towards the end of the war 15 years earlier.
