Brilliant idea for a sequel
22 years later we catch up with Andy and Red who now run a boat/raft building business on the shoreline.
What neither of them know is that the warden had a brother who is hell bent on revenge as he blames Andy for his brother's suicide.
Much of the film is the warden's twin brother putting the pieces of the puzzle together to determine Andy's whereabouts. When he manages to track Andy down, he arrives under the pretence of wanting to buy a boat. Red is suspicious with his mannerisms and way of talking but Andy rebutts him and acts pleasant towards him
He convinces Andy and Red to join him on taking his new boat for a test run as he's a beginner and nervous to go by himself. While sailing, he deliberately heads out to sea until they're too far from coastline.
The second act of the film shifts to a psychological thriller. Andy and Red THINK it was a beginner's mishap but they're still suspicious of this dude.
Eventually Red believes he knows who the guy is, tells Andy who still isn't convinced. Eventually though Andy also agrees. The third act consists of Andy and Red overcoming this guy but sadly Red is mortally wounded.
He dies in Andy's arms. Andy manages to overcome the guy and heads back to the coast (freedom) with Red's body
What is that thing you're using?.... It's technical.
