This time the year is 1943 and the Nazi occupation of the country which followed hot on the heels of the Societ occupation of 1940. It led to the formation of the Latvian Legion as combat units of the notorious Waffen-SS - the results of which resonate to the present day.
"Should we honor or condemn them, keep silent or search for excuses?" the documentary pointedly asks.
According to LTV "The Keys" tells of the most important or "key" events, personalities and turning points in the history of the Latvian state from 1918 to the present. The purpose is to reveal each selected event from an unusual point of view, as if "unlocking the door" to lesser known and therefore particularly intriguing facts.
"Such an exploratory approach, bypassing the usual stereotypes of presenting history, will allow viewers to perceive what is known to others and to better understand what has happened in the context of today's experience," says LTV.
Throughout the year, Latvian history will be told in 'mixed order' - events will not be sequenced year by year, but viewed in the exact month in which they occurred.
The show is made by VFS Films, a long-time partner of Latvian Television and it is hosted by Mārtiņš Ķibilds, a distinguished cultural journalist who sadly passed away late last year.
