His lover Moya mercilessly slain by immortal despot Marcus Octavius, lone warrior Colin sets out alongside wise cracking apparition Amergan on a restless revenge mission in this animated installment of the long-running Highlander saga. It's been tens of centuries since Colin's one true love was taken from him in the flash of a sword, yet the pain of losing her is still as powerful as it was on that damned and fateful day. Roaming the desolate Celtic plains in hopes that dispensing with Octavius will allow him to let go of the hate that threatens to consume him, Colin soon meets up with beautiful but fearsome freedom fighter Dahlia. It seems that Dahlia has some strange connection to Moya, and if only Colin could place it he may come one step closer to solving the mysteries of the past. Now, as Marcus finally crosses swords with the powerful target of his all-consuming vengeance, the fate of the future will be decided by the outcome of a battle centuries in the making.
