Unidentified Following Object (2005)

A nun full of curiosity happened to see a flying saucer in the middle of Zen-meditation. Since then she have expected to see the UFO again at the mountain ridge. But one day master priest scolds her fruitless curiosity. That night she bathed in a pond halfway up the mountain. At that moment, there have been two spectators peeping her... One is a master priest, the other is an alien... What are they doing there at the same time?
