Centurion is British action drama that was written and directed by Neil Marshall. The movie features Michael Fassbender, Dominic West, Olga Kurylenko and Liam Cunningham. In 117 AD, the Romans struggle for power over the Picts in the Scottish Highlands. Quintus Dias, a Centurion is the lone survivor of raid upon a Roman garrison. Taken prisoner by Vortix, Roman governor of Britannia, Agricola, is trying to get in good graces of the Roman Senate. He hopes to be able to transfer back his comfortable Roman life. He sends a message to the Ninth Legion, ruled by General Titus Flavius Virilus to try to end the Pictish threat. He is provided with the aid of Etain, a trained and competent Brigantian scout.
Instead of helping them, Etain betrays the legion to everyone's dismay. He ultimately leads them to a trap where they are all killed. They capture the general as Bothos, Dias and Thax are able to go on with four others to survive.
Macros and Thax run from a wolf pack. When Thax falters, the wolves close in as he cries out for help. Bothos, Dias and Brick befriend a witch named Arianne in the forest. She takes them in and offers medical attention and food. Etain arrives the next day and is confronted by Arianne. The Romans hide in the grain store under the floor. The next morning they depart as Arianne gives them enough provisions so that they may travel to the safety of a Roman garrison in close proximity.
Dias is able to escape the attempt to kill him. He is very wounded in his leg during the skirmish. Agricola's daughter informs him that he is at too much risk. He manages to escape the camp to return to the forest and find safety with Arianne. She is very happy to see that he is still alive and that he has returned to her. They kiss as they lay by the stream.
