Sybille, an accomplished actress, is given the chance to direct a film based on her own screenplay. Everything seems to go well at first. Her producers, two sisters, are two wacky but lovable characters, and Sybille dives into the adventure with them, putting aside her family life. But, from the unlikely choice of actresses, the successive rewrites of the script and the financial issues, the wonderful dream turns into a nightmare. Ever the optimist, Sybille will realise too late that her whimsical and totally crazy producers are going to drag her in their madness ... One thing is certain, nothing will happen as planned.
