Departure

When an airplane disappears over the Atlantic, Howard Lawson of the TSIB chooses Kendra Malley to lead the investigation, even though she's still on bereavement leave; as a potential crash site is identified, Kendra discovers the pilot kept a secret.

The team pursues leads as they wait to see if the surviving witness will regain consciousness; Theo examines the possibility of mechanical failure; marine expert Nadia pinpoints 716's final resting place on the ocean floor and calls the Royal Navy.

Though the flight simulator all but confirms the cause of the crash, Kendra isn't convinced -- especially once Madelyn starts remembering her escape from the plane; Dom suspects that Derek's death was the result of a botched murder attempt.

AJ is injured but alive after his accident; after being attacked, Kendra uncovers a stunning betrayal by someone close to her; a second attempt at reaching the black boxes reveals a new layer to the mystery.

After recovering the black boxes, Kendra investigates Hoffman and brings the full story of the Flight 716 disaster to light.
