Éric and Patrice have been friends since high school. Over the years, they have both taken very different paths: Éric has become a hedonist, has a string of girlfriends and is always on the look out for a new one; Patrice has become a monogamous father with a very ordered life. After a drunken evening, the two childhood friends find themselves cast back into 1986, when they were 17 years old. This return to the past is a dream opportunity to try to change the path their lives will take. What will they do with this second chance?

Love, the Odyssey, life, wars, animals, the destruction of the earth by man. Man is a destroyer, the earth will regain these rights little by little.
