What if loveless sex made us sick? The very strange, very French world of Mauvais Sang

Mauvais Sang – Bad Blood in English –orbits the outbreak of a disease, STBO, which is contracted during sex if at least one person does not love the other. When his father dies, Alex – a stoic ex-con and amateur ventriloquist teasingly nicknamed Chatterbox – inherits his destiny. Summoned by his dad’s crook friends, Marc (Michel Piccoli) and Hans (Hans Meyer), Alex is coaxed to steal the STBO antidote, to be trafficked by shady US forces. This task propels him towards Anna – mob boss Marc’s ingenue girlfriend, played by Juliette Binoche with a magnetic, moony intensity – while the devoted Lise, whom Alex has cast aside, hovers on the outskirts.
