My Pastor Among the Thais(1983)

Original title: Mon curé chez les Thaïlandaises

Maximin, priest in a little village in the South-West of France, inherits from his brother a brothel in Thailand, although he's always been told it was a very strict catholic school. The journey to Asia is full of surprises (a plane hi-jack, pirates...) and once in Thailand, Maximin is taken into 'political' turmoils.
