Synopsis:

In 1845 Canada, young James Howlett sees his father killed by groundskeeper Thomas Logan. The trauma activates the boy's mutation: bone claws protrude from James' hands, and he kills Logan. In his dying breath, Logan tells James that he is his real father. James flees with Logan's abused son and brother Victor Creed. The two survive for over a century as men in their prime, putting their violent urges and skills to use by fighting in the American Civil War and both World Wars. During the Vietnam War, Victor kills a superior after he stops his rape attempt of a local villager. James defends his brother, and the two are "executed" by firing squad. They are locked up in chains after the execution fails due to their regeneration powers. Major William Stryker approaches the two and offers them membership in Team X, a group of mutants including marksman Agent Zero, mercenary Wade Wilson, teleporter John Wraith, invincible Fred Dukes and electrokinetic Chris Bradley. They join the team, but the group's questionable actions and disregard for human life cause James to leave. Six years later, James - now going by the name Logan - is living in Canada with his girlfriend, Kayla Silverfox. Colonel Stryker locates Logan and warns him that someone is killing members of the team. Shortly afterwards, Victor murders Kayla and brutally beats Logan. Stryker offers Logan a way to beat Victor. Logan undergoes an operation to reinforce his skeleton with adamantium, a virtually indestructible metal. Before the procedure, Logan asks for new dog tags inscribed with "Wolverine"-- based off a story that Kayla told him. Stryker orders Logan's memory to be erased, but Logan overhears and flees and kills several guards, with former team member Zero tracking him. Wolverine takes refuge in the barn of an elderly couple who take him in for the night. Zero brutally murders the couple and attacks with two hummers and a helicopter, but Wolverine subdues and kills him and his men......
