In the summer of 1979, gay porn producer Anne sets out to film her most ambitious film yet, but her actors are picked off, one by one, by a mysterious killer.

On a chilly Sunday morning, a man awakens to the mischievous stare of a unicorn that seems to have come straight out of his dreams. Carried along by an early morning sensuality, his fantasies transform his lonely apartment into a garden of delights, in which this young creature can freely reap the fruits of his desires.

Richard, a 40-year-old filmmaker conquered by an unexplained anxiety attack, lets go of his current shoot and wanders through nocturnal Paris, in search of answers, solace and inspiration. During this sleepless night, at random encounters, sometimes warm, sometimes disturbing, crossing foreign figures, unknown bodies or familiar faces, Richard will face his fears and question his deep desires... until dawn.

Several people lend their lips to the director.
