Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
Cléo, a French singer, is walking on a sidewalk in Paris when she stops to watch a man swallow a frog. He has a small tank in which there are many frogs. He takes one at a time and stuffs them head first into his mouth. After we see him swallow 3 or 4 of them, a huge amount of water explodes from his mouth. We don't know why he's doing this, but it's probably street entertainment he does for spare change. I don't know my French frogs. They're most likely marsh frogs or pool frogs, or their hybrid, the edible frog.)
