Barcelona, 1967. Hans Fromm, a German-born architect, lives an well-ordered everyday life. He has become the target of an antifascist death squad though. Indeed their leader, Julius, whose brother was killed by Schmidt, a merciless S.S., believes, without being absolutely certain, that Fromm and Schmidt are the same man. The team, whose other members are Georges, the son of a deportee liquidated by Schmidt craving for action, Raphaël, a mercenary type, Nils, the photographer and Romain, watch Fromms every move until Julius, convinced at last that the quiet German is their man, gives the green light for the operation. They manage to lure the former Nazi to an old house but Schmidt/Fromm wont let himself be captured so easily...
