MoviesOnline have the synopsis for the Rambo sequel, starring none other than Sylvester Stallone.

Lionsgate Films just provided us with the official synopsis for “John Rambo”. Sylvester Stallone writes, directs, produces and stars as John Rambo, filmed on location in and around Chiang Mai, Thailand. Also starring are Julie Benz (”Dexter”), Matthew Marsden (”Resident Evil: Extinction”, “Black Hawk Down”), Graham McTavish (HBO’s “Rome”), Rey Gallegos (”American Wedding”), Jake La Botz (”Ghost World”), Tim Kang (”Third Watch”) and Paul Schulze (HBO’s “The Sopranos”). In Thailand, a group of Christian aid workers recruit John Rambo to guide them up the Salween River to deliver medical supplies to the Karen tribe of neighboring Burma (aka Myanmar). When the missionaries fail to return, Rambo is persuaded to take a group of mercenaries back into the war-torn border region to find them. What follows is a descent into hell on earth.

Also, here is the trailer in case you haven’t seen it yet. It’s incredibly gorey though, just so you know.
