Sylvester Stallone is back as John Rambo twenty years after the last Rambo movie, so as you would expect has retired and is living in Thailand. He is living on the border right next to the Thai-Burma where there has been a civil war which has been running for sixty years. But Rambo now lives a simple life running a longboat on the Salween River and does not want to get caught up in any fighting. For years he manages to stay out of anybodies way, which is until a group of human rights missionaries ask for John Rambo to become their American river guide.
Both Sarah played by Julie Benz and Michael Bennett played by Paul Schulze approach John and say that they are not able to make it to the refugee camps by foot as there are too many landmines, so they need to be able to make the journey by river. At first Rambo refuses to be their guide he then decides to help them by dropping them off as close to one of the villages.
Two weeks later Rambo learns that the two missionaries have not returned and that the congregation has now hired mercenaries to try and free both Sarah and Michael, with this news John Rambo knows what he must do and that is when all the ass kicking begins.
