Des nouvelles de la planète Mars

Philippe Mars wants to please everyone. He wants to be a good father, a friendly ex-husband, a helpful colleague and an understanding brother. Unfortunately, his little world goes out of its planned orbit. His son becomes a hardcore vegetarian, his daughter a compulsive swot, whilst his sister exhibits giant paintings of their naked parents. At the office he must face the rampages of his mentally unstable colleague Jerôme who one night turns up at his door with a young woman in tow who has just been released from a clinic.
