Jamie-Lynn Sigler Gets Disturbed in 'The Neighbor in the Window' (PHOTOS)

When upbeat, outgoing Karen (Jamie-Lynn Sigler), her husband Scott (Geoff Gustafson), and their young son relocate to Washington for Scott’s job in The Neighbor in the Window, Karen looks forward to starting a new life.

There, she meets Lisa (Jenn Lyon), her beautiful, charming neighbor and the two quickly bond. But Lisa soon starts lying to Karen and about Karen to others and every aspect of her new life starts to unravel. Inspired by the book False Victim by Kathie Truitt, the Lifetime original movie premieres Saturday, February 8.
