La Turbulence des Fluids (Canada, 2002)

This film from Québec explores the possibility of a drastic change in the tide waves along the St. Laurent river. A woman specialist is called to investigate. She travels from Japan back to her hometown, Baie Comeau, in Québec, to help scientists understand this strange phenomenon. During her stay in this small city, she gets to meet interesting characters, along them a mysterious Marc Vandal, for whom she quickly falls in love. In the meantime, everyone in town seems to have been affected somehow by this sudden stop of tidal waves, in their personality and state of mind. We soon realize that Marc has a tragic family story behind him, which I will not write here because I would be giving off the whole story. The final earthquake sequence tells us this story is quite implausible, though a very interesting and suspenseful one.
