Although Sloane "urges" her to stay on
leave, she's determined to save Will.
In a hidden location, Peyton's accomplice Burris injects a bomb
into Will's neck. Meanwhile, Sloane tells Sydney that Echelon has
intercepted a call between Yerik Semanko and Anna regarding an
exchange at a Moscow club run by the Russian mafia. Sydney leaves
her baby with babysitting agents.
In Moscow, Dixon, Rachel and Tom enter the club with Marshall's
help. Sydney accesses the club through the roof. Once in the club,
the team dons eyeglasses that broadcast x-ray images to Marshall,
enabling him to spot guns and money. Later, Rachel flirts with
Semanko while Sydney skilfully plants a bug on his collar. As he
goes into the VIP room and meets Anna, the APO team overhears that
Will is in Room 147.
Syd heads toward Will and confronts Anna. Peyton watches the fight
through video surveillance. Anna knifes Syd's arm - and the camera
scans Syd, capturing data. Will helps Syd chase off Anna.
In the APO
office, Sydney tells Jack that she hated telling Will that Vaughn
was dead. Jack reminds her that Vaughn's safety depends
on hiding him. When Will visits Syd, an alarm notifies the babysitters.
Later, they discover the bomb in Will's head. Suddenly, Syd gets
a call from Anna.
Anna asks Syd to hand her Page 47 of the Rambaldi manuscript in
exchange for the bomb's deactivation. When Syd notes that handing
over the page will not guarantee Will's safety, Marshall suggests
that he can build a device that can track the bomb frequency and
reverse engineer the activation. The only catch is Will has to
be close to the detonator.
On a train In Lisbon, Will asks Sydney to be the best man at his
wedding. They then tap into the train's security system and find
Anna. To bring Will close to the detonator, Syd meets with Anna
for the trade. Syd gives her Page 47, but Anna begins the countdown
and Will's head beeps. Syd steals the detonator and stops the countdown.
Anna escapes and locks Syd in the car. Suddenly, Syd is showered
with red liquid. Anna calls Peyton and confirms that Sydney's DNA
is being collected.
Will knocks out Anna and frees Syd. Anna recovers, activates another
detonator and throws it off the train and into a lake. Syd and
Will dive into the lake. Syd finds the detonator in time to deactivate
it and once again save Will's life.
Sloane meets with Peyton and she assures him that Sydney wasn't
hurt in any of their experiments. In exchange, she hands Sloane
a chemical compound that could save Nadia. Meanwhile, Will and
Sydney walk through a park where Syd apologises for the chaos she's
brought him. Will assures her that it is not her fault that evil
people that exist, and that he sleeps better knowing that there
is only one Sydney who can keep the world safe.
In Moscow, Anna enters a tank filled with red liquid. She emerges
with Sydney's face.
