Devant came out on top in a muddling renewal of the Group Three Prix Miesque, at Maisons-Laffitte.
A field of ten juvenile fillies went to post for this seven furlong contest.
The grey Primela was the early leader with Epistrophy, but the early pace was not strong.
Primela and Epistrophy continued to set the tempo, with Happy Odyssey in behind and then Amber Spark.
Epistrophy pressed on with two furlongs to race, but had not shaken off her rivals.
The final furlong saw the complexion of the race completely change.
The leaders were quickly passed and So Unique hit the front, but was soon passed by Devant and Pierre-Charles Boudot, with So Unique also finishing with a rattle, to the stands side.
But Devant, a daughter of Showcasing, kept up the gallop to hold on by about half a length from Stay Classy, with So Unique a close third.
