Some military assassins invaded a world summit and shot the speaker.  These assassins are at a high threat level, and Albania and Serbia are blaming each other.

Director Trilby wants to bring in the legendary assassin, the Wolf, to help them. Harry is hesitant, but Luther and Maria are excited.

Harry is ingrained in his work he doesn't notice Helen in lingerie. No wonder she feels ignored.

Helen meets the Wolf, aka Nathan, at lunch the next day, and they bond about being misfits. The Wolf also hits it off with the rest of the team, except Harry, at the meeting and thinks the assassins wanted to start a war and sell more weapons.

Harry gets jealous and upset when the Wolf gets past his home security and offers to help Helen in weapons training. Harry wants to get rid of the Wolf now that he's identified a suspect, but Gib says they need him.

The wolf fears he's broken, but Helen reassures him of his good qualities. Harry hates this friendship.

There is a stake-out by the ambassador's house. The assassin arrives in a driverless truck, and while they destroyed the explosives, the war is on.

The Wolf overhears Harry call him a murderous psycho. Harry apologizes as the two head to a warehouse to check for assassins.

Helen realizes they're heading into a trap, and the assassins are inside. They rig the escape fan to suprise them, and then Harry and the Wolf begin shooting.

It looks like the Wolf might shoot Harry, but he saves him instead.

Since Helen's intel saved them, she's now a full team member.
