As Syd prepares
for her graduation, Sloane calls, ostensibly to congratulate
her. He admits he knew she and Jack were double-agents and
that he used them to free himself of The Alliance. He warns
her not to get in his way. At the CIA, Kendall briefs Syd on
Sloane's kidnapping of Caplan, whose knowledge of Knot Theory — how
geometric objects fit together — would enable Sloane
to build a weapon out of the Rambaldi artefacts. Syd wearily
realises the battle against evil is eternal, and rethinks her
resignation.
Sydney tells Dixon that he's been cleared, and offers him a
CIA job. Dixon, however, feels manipulated by Syd and never wants
to see her again. He goes home to his wife and confesses his
life of deception.
Despite his vow to be honest with her in the future, she later
says that she'll leave him if he joins the CIA. Marshall, on
the other hand, has already adapted to the CIA and has found
a Sloane associate — Holden Gemler, a cybernetics specialist
in Van Nuys. Jack discovers Gemler's body, sans one eye, during
a search. Marshall reveals that the eye is actually a tracking
device and they deduce that Sloane hired Gemler to deactivate
his own Alliance-implanted tracking device. Marshall accesses
the memory in Gemler's eye, which shows Sloane killing Gemler
and mentioning a chartered C-123 cargo plane from Shipman.
Shipman is a smuggler-operated airfield in the Mojave Desert.
With Vaughn posing as an arms dealer, Syd sneaks in and downloads
the plane's data recorder, which will reveal Sloane's final destination
as Switzerland. Syd repels an attacker, sending him into the
plane's propeller.
With Caplan agreeing to help Sloane in order to save his family,
Sloane plans to break into a Zurich bank that holds Caplan's
invention, a magnetometer, which can measure magnetic fields
and fit the Rambaldi pieces together perfectly. Sloane talks
to Emily, telling her that their Tuscan villa will be ready in
a few more days.
In Switzerland, Vaughn contacts a mercenary employed by Sloane
and nearly sets him afire before he reveals the location of Caplan's
wife and child. With the family rescued, Syd has Marshall triangulate
the calls from a cell phone she found on a kidnapper and finds
that they originate from the Zurich bank. Syd and Vaughn race
through the streets to get there in time.
At the bank, Sloane, who has changed his appearance to that
of an elderly man, gains access to the vaults under the pretext
of making a $50 million deposit. He shoots the bank manager and
finds the magnetometer. Syd and Vaughn arrive as Sloane and his
team are leaving. The standoff is broken when Sloane says he
has rigged the lower level with enough C-4 to destroy a city
block and if he doesn't exit in 30 seconds, an off-site team
will detonate it. Sydney and Vaughn toss their guns to the ground.
Sloane throws Sydney a set of keys, telling her that she will
drive him out.
