Planned as the fifth HES generating power from the flow of the Daugava, it never made it off the drawing board and into reality, and the documentary traces why that was the case. There is also a fascinating brief history of the other power plants along the course of the Daugava.
Protests against construction added to the weight of public opinion pushing for the end of rule from Moscow, even though they were ostensibly more about environmental protection than political ideology.

According to LTV "The Keys" series 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.
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.
