It's like Vikings but about the different kingdoms of the Brits getting their shit together and uniting to fend off the Danes. And one Brit boy kidnapped by Danes who grows up a Dane and as a grown warrior has to decide which side is his to fight for. Your blood heritage and ancestral entitlements in your own motherland where u are considered an heir. Or family friends and fatherland where you are promised nothing more than being known and respected as a great warrior. BTW the Danes killed are your family while raping and pillaging which is how you became an orphan in the first place. And you saw them do it. But now you are a pillaging Viking too.
