When a documentary crew traveling through the Amazon jungle, picks up a stranded man, they are unaware of the trouble that will occur. This stranger's hobby is to capture the giant Anaconda snake, and plans to continue targeting it on their boat, by any means necessary.
Julie's boyfriend Ismaël lives with her; rather than worry about the time he spends with his colleague Alice, Julie invites Alice to join them. The three walk the streets of Paris, party, read, and sleep together. Sometimes it's lighthearted, sometimes there are jealousies. Then death strikes. In various ways, those left come to terms with the departure and absence of a loved one: showing concern, eating together, attempting new relationships, trying to "be there" for the other. Then, the spirit returns and new commitments are possible. The romantic elements of musical comedy play in contrast to the ambivalence of the lyrics and the story.
