“Embrace of the serpent” actually tells two stories. Bijvoet plays the scholar Theo who spends much of his life in the Amazon rainforests to investigate the people who live their and the things that grow there. During his travels he built good bonds with some locals. When he gets sick he is escorted to “the wandering shaman” who takes him to the mountains where the Gods reside in order to find a special plant to cure Theo.
The other story plays many years later. Evan follows Theo’s tracks to look for the same cure. He travels with the same shaman.
In both stories there are an open-minded Westerner who travels with a native and an ‘in between’ (a native who has lived most of his life with Westerner). Of course cultures clash, but all parties learn from each other.
The story may not be very original, but it is based on true events, so nothing can be said about that. The time of adventure films in exotic cultures is mostly something of a decade or two ago, but Guerra managed to make a descent contemporary one.
