Self-important, over-dramatic, uninspired.

One of the worst movies I've ever seen

It really made me laugh, but for some moments I was tearing up because I could relate so much.

This is a small, humorous movie in some ways, but it has a huge heart. What a nice experience.

Tonatiu, a distant planet in the Pleiades is plagued by diseases brought from Earth. Two agents from Tonatiu are sent back to Earth, in order to find a mysterious South American tree called "bororo" that is mentioned in the notes of Czech adventurer Alberto Vojtech Fric (1882-1944). An extract from this tree is able to kill many species of terrestrial bacteria within an astonishingly short time. However, they are not the only ones that are interested in the phenomenal attributes of this tree, and their mission ends tragically...A movie that has stayed in my memories since childhood. It had a very specific, mysterious atmosphere that I couldn't forget. As an adult, I would rate it more critically, but still, it is not an ordinary film. It has a great music composed by Petr Hapka, and the grace of young Božidara Turzonovová (as an extra-terrestrial woman) also adds a lot to its exceptional impressiveness.

Not bad Sci-Fi movie. Everybody hunts for mysterious pill (panacea). The scientist wants to present medicine to the mankind. Bandits to use it as the weapon of mass defeat, and aliens are to rescue one's civilisation...Filmed in specific "soviet-like" manner: no blood, no sex, etc. and it is in spite of presence of gangsters and romantic attitudes between the main heroes.My only complaint is that the plot develops not enough dynamically.If to take into consideration that it is "Barrandov studio", instead of "Hollywood" with its budgets and that it is beginning of 80s, then it is possible quite to say that the movie turned out qualitative not looking to small-sized deficiencies, but addressing entirely to the main idea.
