1x7 - Lost Signs

When he awakens, Lorenzo is overcome with terror. He recalls the images of the plane trip: the turbulence, the plunge into the void, the passengers falling asleep and a strange blue light. Laure and Xavier consult the archives of that period and track down the stewardess. She too has a scar on her forearm, but her implant was surgically removed. Laure returns to the army center and manages to sneak in a USB key on which she records the list of passengers- all but one, who remains unidentified. Erika panics when she hears what Laure has found out: all the children of the passengers on Flight 173 have disappeared. Which means that Lucas, Lorenzo's son, is in danger of being abducted.
