PLOT
This German format is not a series properly speaking, as it has no permanent cast or script continuity, but presents each time a 45 minutes documentary, usually in part presented as a docudrama (not faction, as close to scientific knowledge as possible, but visually attractive), elaborating a specific historical theme, widely varied, often exotic in the sense of a far time (as far back as prehistoric times) and/or place (around the globe), although some episodes fit together well, chronologically or thematically, but always fit to be watched separately. Usually authentic locations are used, as well as scenes from and/or interviews about the scientific research it is based upon.
