Ultimatum is the last of the Bourne trilogy films. Here Jason was back, among others in Europe, on the search for his past. CIA tried to stop him by all means, but due to an internal conflict, some (including Nicky, again) tried to help him. You'll be following his journey and his struggles with a couple of flying bullets, dangerous car chasing, intense hand combats, as well as puzzles solving.
Ultimatum is, without doubt, the best of Bourne ever. Recommended.
