Unsettling thriller starring Maggie Gyllenhaal in her finest performance yet.

Maggie Gyllenhaal stars as a woman obsessed.

Dissatisfied with family life and with her work, she aspires to becoming a celebrated poet, but fails in her efforts.

When one of her pupils shows himself to be a wordsmith and a poetry prodigy, her interest in his progress takes on dark undertones.

Equally mentoring and manipulating, the plot gets tighter and tighter.
