A banker has died. He trafficked in nuclear material, so French intelligence assign two agents to find his list of contacts, which are on a flash drive: Muriel - the boss, acerbic, willing to sleep with any man, wondering if she should have a child - and Philippe, younger, boyish, meticulous, bothered by Muriel's frank sexual interest. They watch Constance, the banker's widow: a naïf, friendly, open, trusting. She's taking opera lessons, so the French spies join the class, which Muriel enjoys. (imdb)
