To regain the one he loves and his children, Alex Meyer, composer and director of musicals, hard hit by his marital breakdown dating back three years, decides to rebuild himself.

When Alex Meyer, director of a musical, finds the inspiration he had lost since the break with his wife, it is his producer who gives up following him: in this profession three years of absence is very long, too long. But Alex, determined, and even secretly hoping that this show could allow him to win back the one he loves, will then attempt the impossible: to "tear him up" in a warehouse loaned by a friend, by giving their first luck to young talents and especially with the complicity of Matthieu, this gifted young composer he has just discovered.
