Jack and Dixon recall that it was an SD-6 mission that took place in a French territory. Jack then assigns Dixon to fly to France and contact Renee Rienne. Jack also directs Sydney to go to a safe house.

Irina waits for Syd at her apartment. Irina admits knowledge of Prophet Five. She says that Prophet Five wants to pursue "The Horizon," which they believe Sydney knows about. Sydney says that she doesn't but that she had shared the name of the French mission with her father.

Despite Devlin's ongoing investigation, Jack enlists Marshall's help to break into their archives and look up a contact for the "Leo-47 Norte" mission. He finds out about Jean Bertrand's involvement and forwards this information to Dixon. With Renee Rienne, Dixon forces Bertrand to reveal more about The Horizon, which is stored in a safety deposit box in a Vancouver bank.

Posing as an Italian family, Irina, Jack and Syd infiltrate the bank. As Jack and Irina inquire about safety deposit boxes, Syd hacks into the bank manager's computer.

With Rachel's help, Syd locates The Horizon's box and relays the info to Jack. Irina tranquillises the manager and starts to work on retrieving The Horizon.

With the lead that Irina had provided them, Peyton and her armed men from Prophet Five arrive in the Vancouver building and kill the guards.

With the Horizon -- which is booby trapped -- in Jack's hands, Irina attacks him. Jack deflects her as Syd enters. It dawns on Sydney that Irina orchestrated her abduction for Prophet Five. When Irina insists that Peyton will kill her too, Jack responds by saying he will kill Irina first. Suddenly, Sydney's contractions begin.

Believing she's helping Jack and Syd, Rachel, under Sloane's direction, deletes records of Sloane's outgoing transmission to his Prophet Five contact.

With Peyton's team on the move, Irina leads Syd and Jack to the roof, where a helicopter will extract them. Peyton watches them on a surveillance camera. She picks up a rocket-launcher and blasts the copter to pieces. Jack tells Syd to keep a gun on her mother as he goes back down to fight Peyton's team. After killing her henchmen, Jack squares off with Peyton. He takes aim at a nearby fire extinguisher, which explodes, killing her. Or so he thinks.

Irina tells Syd that the KGB forced her to bear Jack's child to ensure his loyalty. When Syd was born, she says, she had to choose between being a good agent or being a good mother -- or fail at both. She chose being a good agent. At this moment, Sydney goes into labour.

Jack arrives to calm Sydney down as she goes into labour. With both her parents' support, Sydney delivers a baby girl. Irina bolts with the pouch containing The Horizon, while Sydney and Jack swaddle the baby. Marshall receives a call from Irina, who tells him that Sydney and Jack need extraction.

In Bhutan, a horseman speeds to an isolated hut by the hillside. He relays a message to a monk sitting calmly in the middle of the room. The monk then walks to another room and shares the news of Sydney's infant daughter with a fellow monk….Michael Vaughn!
