Museum curator Brock Turner has his cozy life turned upside down when he comes into possession of a mysterious medallion. Teaming up with his best friend, he sets out to learn where it came from and why people are willing to kill him and steal it. He soon discovers that it leads to the final resting place of Excalibur, the legendary sword of King Arthur. Joining the race is a beautiful English spy, who has a dangerous secret of her own. She agrees to protect Brock on his quest to find the sword before a Russian seductress and her band of goons find it first.
