History Channel hit show Vikings season 2 will airing its finale episode Thursday, May 1 at 10 p.m. ET.

The official synopsis for episode 10, entitled "The Lord's Prayer" is as follows: "Ragnar and King Horik return to Kattegat and the final showdown between two Viking leaders is at hand. Ragnar has placed his trust in those who have stood by him and now the time has come for new alliances to be made."

If you miss tonight's episode on the History Channel, the finale will also be available to watch online via live stream for free on The History Channel website.

The Vikings series has been renewed for season 3. Regarding the future of the show, creator Michael Hirst told Time Magazine: "In Season 3, I think we have to up the game again, and Season 3 will certainly feature a very famous event which was their first Viking attack on Paris that Ragnar led. It's the most extraordinary episode.

He continued, "We've got over 100 ships in Season 3. And we're going to attack Paris. So it's fantastic. I thought that it was reasonably clever to focus on a central character who had lots of sons. So, I therefore hoped that if things worked, that we could do Ragnar and then we could do the sons because one of the sons, for example, Bjorn, sails around the Mediterranean. I mean, they attack what they think is Rome. They go to Spain. They do extraordinary things. I was always optimistic that we could go forward. But on the other hand, you never know."

The green-light for season 3 given last month, and production is set to begin in the summer for a 2015 premiere date.
