I think I'm one of the few who still watches Nickola. I understand that, because it's not easy to follow if you don't speak Polish. And I don't, so I translate the forum and the comments with Google Translator. Season 1 of Nickola ended today so I thought I would give you all a summary.
The first 40 episodes, were just about Nickola and her friends. Around episode 40, a second storyline was introduced. A journalist, named Ursyn, discovered the existence of the HoO. His boss investigated the HoO and was murdered while doing that (mmm, I wonder who did that?). Ursyn took over the investigation and discovered more about the HoO and the Order. He was helped by a photographer named Lambert (also called the Python), by Ewa (another journalist, sort of Ursyn's girlfriend) and by Karolina, who is a specialist in lip-reading. They discovered that Nickola was the next trait positive soon-to-be victim of the Order. So they started to look for her.
Nickola and her friends also discovered that Nickola was chased by the Order. Especially because of a mysterious man, named the Sphinks who gave her information about the Order. It's still unclear what his intensions were/are, because he also had some connections with the Order. But he helped Nickola (and later on Ursyn and friends) a lot.
How did the Order got Nickola? A while ago, the Order murdered Nickola's best friend (Kama), because she had done some research on the HoO. And, like we all know, The Order don't like these kind of investigating kids, so they killed her. Easy as that. Nickola didn't knew Kama was killed. Someone told her that Kama had been in some sort of car accident and that she needed a blood transfusion from Nickola. Very suspicious huh. So Nickola went to the hospital and, ofcourse, The Order got her. They apparently gave her a very strong anesthetic because Nickola was seen lying in a bed unconcious for weeks. Eventually she woke up and her Elder (Harald, also called the Man in Black)used her for his ceremony. We don't know if Nickola died at the ceremony but with Bree in mind, we can assume she's dead.
While the ceremony was taking place, Ewa (one of Ursyns friends) was captured by the Order. They placed her in a cooling unit. She was in there for a few days and then they brought down the temperature in there and she frooze to dead. Ursyn and Lambert discovered where Ewa was held but they came too late to save her. Lambert was shot by a shadow and Ursyn wanted to kill himself because he failed to save Ewa.
And then we are at the last episode of season 1. We see that Lambert survived the shooting and that Ursyn didn't kill himself because he was pulled away while he fired his gun, probably by someone from a Resistance group. Resistance group? Yes, it seems that there's a Resistance group, lead by a man named Eric. Eric gives Ursyn a bunch of photo's and on one of them is Jonas. It seems that Eric wants Ursyn, Lambert and Karolina to join his group. And there the season ends.
Nickola also has some sort of behind the scenes section on their website. Here's the link to the little article that saids that season 1 is over (I've already put it in google translator): http://translate.google.com/translate?prev=hp&hl=nl&js=n&u=http%3A%2F%2Fn1ckola.pl%2Fza_kulisami.html&sl=pl&tl=en&history_state0=
I tried to give a summary about the last few weeks of Nickola but, like I said, I'm not sure about some things. But this pretty much sums up the most important things that happened. I must say, I really like this show even though I don't understand what the characters are saying. Hopefully in the second season, the subtitles will come (yes Eqal, take notice of it).
