Persons Unknown

The Edge

While the group attempts to understand why they were kidnapped, Moira painfully removes the implant device that has been embedded in each person's thigh. Elsewhere, trying to escape back to their normal lives, Joe and McNair carefully test the limits of the invisible fence. Meanwhile, back in San Francisco, curious reporter Renbe's search for information on missing mom Janet hits a dead end.

The Way Through

After a week of escape attempts end in failure, tension begins to grow within the group. When a helicopter appears above the hostages, they are hopeful that help has arrived, but the craft only hovers long enough to drop a mysterious box. Meanwhile, San Francisco reporter Renbe puts himself back on the case of Janet's disappearance, despite warnings to stop his investigation.

Exit One

The Night Manager informs the group that one of them will be allowed to check out. Meanwhile, Joe has a secret meeting with someone in the town, and Tori receives a visit of her own.

Incoming

After discovering that Tori is missing, the group's search for her turns up a mysterious newcomer with the name "Erika" tattooed on her arm. Erika reacts violently to her new surroundings and physically attacks Joe, Janet, Blackham, and Moira. Meanwhile, a suspicious Renbe believes he's found a link between Tori's fate and Janet's disappearance.

The Truth

When Joe suddenly falls violently ill, the group becomes alarmed. Meanwhile Erika discovers an antidote, but refuses to give it to Joe unless he comes clean about his secret. Elsewhere, reporter Renbe and Kat attend Tori's funeral in Rome and discover that her father, the U.S. ambassador to Italy, is also investigating her disappearance.
