I've seen this show many times as child. Four travelers in time have to retrieve a notebook containing notes crucial for saving of Earth. Despite the effort put in their study of 20th Century Earth, sometimes it is hard for the 24th Century people to stay inconspicuous, which leads to many, rather funny, situations. The show is with its idealistic vision of future Earth as peaceful place where the nations no longer fight each other best comparable to the Earth seen in American show "Star Trek". The reactions that heroes had to the 20th Century is similar to this that heroes of the old show "Galactica 1980" have when the Battlestar Galactica finally arrives to Earth. If you enjoyed the shows mentioned above, it is possible that you will enjoy this one as well. This show still remains to be the only sci-fi series made in the former Czechoslovakia and even in now-a-days Czech Republic.
