A Ukrainian woman named Irena calculatedly insinuates herself into the lives of a young, affluent Italian family. Stopping at nothing to become the couple's trusted maid and the beloved nanny to their fragile young daughter, Irena risks everything in her quest to uncover the truth about the family.

If it's occasionally manipulative, this Italian melodrama mixes thriller conventions with a poignant love story and keeps the tension rolling from start to finish.
