This is a continuation of the first Bourne Movie. After a mistake during a CIA mission, Jason Bourne (Matt Damon) is forced back into his life as a secret agent. He said at the end of the first movie that if anyone from the CIA contacted him then he would get revenge. That’s exactly what he does.
If you liked the first movie then you will like this. Plain and simple. Some movies have made bad sequels (Matrix) but this is one of the good sequels.
Recommendation: Buy if you liked the first one.
Tomorrow finishes off the Bourne Trilogy.
