Meanwhile, Tom goes to the Payroll Department to complain about a missed pay check. Rachel, pretending she has an interview, leaves her cell phone with the guard. The cell phone is actually a device that infiltrates security. Tom commandeers a Payroll Dept. desktop and, using the data sent from the cell phone, grants Rachel security access to the CIA server room. He also unlocks the Witness Protection records room.

Marshall distracts onlookers by announcing he's cracked the code that appears on a monument. Dixon sprays a surveillance camera, causing an "Anthrax alert." Rachel then slips into the server room but finds that Syd's transmission was purged. Jack tells her to pull the hard drive, knowing that it will raise the alarm and cause a lockdown. He calls Weiss for help.

Weiss arrives and apologises to Dixon, whom he calls "Ambassador." While he escorts Dixon and Marshall out, he gives Dixon the key to get Tom. Marshall ducks into an office, locates Rachel with surveillance cameras and guides her through a maze of servers.

On the boat, Syd holds Peyton at gunpoint and asks her to explain the ultrasound images posted in a room. She faints, however. She wakes to find herself being prepped for surgery.

At APO, Marshall and Dixon inspect the hard drive and discover that the person who purged the records had Alpha Black clearance. Only seven directors have this clearance. They also find the secured cell phone numbers that enable these men to access the code. Marshall says he can trace which phone was used to access the server.

Tom uses Marshall's PC to decode the info he downloaded from the Witness Protection records. The data contains photos of his murdered wife along with the name and location of a man. Later, Tom pays a visit to the man.

Jack convenes a meeting with the seven directors, Marshall locks in a match and calls that phone. When Director Davenport's phone rings, Jack immediately shoots him and forces him to divulge Sydney's whereabouts. CIA security arrests Jack.

The doctors perform an amnio on Syd and decide to operate. Dixon arrives on the ship and realises it's abandoned except for the infirmary. He spots the post-op Syd and takes her to the helicopter.

At the hospital, Jack tells Syd that the baby is fine, that the mysterious surgery actually corrected a placental abruption. After a few minutes, an armed guard tells Jack that it is time to go and a confused Sydney says reluctantly goodbye to her father.
