The Stitcher team investigates twelve mysterious deaths on the same red eye flight into LA. With time running out before they have to release the surviving passengers, the team makes a dangerous multi-Stitch. Meanwhile, Kirsten makes contact with her half-sister Ivy.

Defying Mitchell's orders, Kirsten continues her investigation to find her father. She discovers that her mother Jacqueline is apparently still alive, but the Stitch into her caretaker's mind leaves Kirsten in a precarious position.
