Elizabeth Olsen starrer Therese Raquin has a new name and an official trailer courtesy of Roadside Attractions, Deadline said.

Now titled In Secret, the period drama stars Olsen as Therese, the young sexually repressed heroine of Emile Zola’s 1867 novel who finds herself trapped in a loveless marriage to her cousin Camille (Harry Potter‘s Tom Felton). When Camille’s artist pal Laurent (Oscar Isaac) comes to visit, adulterous sparks fly hurtling Therese down a path of obsession, love, and madness.

Roadside has set a post-Valentine’s Day release for February 21, 2014.
