When Lily and Jane go missing one night after a party, ex-cop Luke Carillo does whatever he can to try and find them. He ends up undercover on an island run by the drug trafficker who was responsible for the attack, alone and without backup. Before he can get any evidence to lock the assailant away, he runs into Alex. Alex Johnson is an assassin. Her blade doesn't discriminate until she runs into Luke and for some reason, she hesitates. She can tell something is different about him, but she doesn't know what it is until he drops his entire mission to save her life. Eventually, they form an alliance in order to survive, but each has a different mission. Luke wants to find the girls that were abducted and return them to their families. And Alex? She just wants revenge.

Emerging from the river mist, theater student Ella finds that she is no longer in the year 2019, but has slipped through time and space, landing in the year 871 AD in England during the time of Viking invasion. Dressed in a Medieval costume for a college performance of 'Hamlet', she is mistaken for a lost Saxon princess, Aethelthryth of Northumbria, and is taken hostage by a raiding party of Danes. Their leader, Thorvid, is young and ambitious. Eager to prove his worth to his older half-brother, Ivar the leader of the Great Heathen Army, he sends the request directly to the newly crowned King Aelfred of Wessex for a rich ransom and decides to deliver her to the English king himself. Aelfred is destined to become one of the most renowned rulers in English history, known for his militaristic savvy, his scholarly pursuits, and his piety. When they reach Uintancæstir, called Winchester in modern times, Ella is torn between the Danish warrior and English ruler as they maneuver around each other in volatile times where the risk of betrayal can not only cost your life, but your soul as well.
