I watched Mechanic Resurrection.
This is the story of Stratham who plays the mechanic who is good at killing people. An evil-doer enlists the mechanic by sending in a woman who Stratham rescues from an abuser and then re-kidnapping the woman.
Stratham is asked by the evil-doer to kill 3 people and make the killings look like accidents. Stratham kills the first two and fakes the death of the 3rd person and then attacks the evil-doer and rescues the woman.
By the way here are a few photos of Jessica Alba as the woman who is bait for Stratham . . .
