Jack, Sydney, Irina, Vaughn and Nadia parachute into Sovogda, Russa to dismantle the giant floating red ball of the Circumfrence which is turning people into mindless, red-eyed zombies out to kill. Back at APO, Marshall and Weiss try use the Blackwell Index to blackmail the Russian defense minister into giving them the access codes to a Russian satellite before the local authorities plan to drop a nuclear bomb on the city to destroy it and prevent the spread of the contagion, and they also discover that Elena is up linking the satellite. In the ruins of the city, a CIA agent, Brodien (the one whom Sydney rescued from Shanghai in the season opener) reminds them that the Rambaldi device is broadcasting a sub audible frequency that physiologically alters people who drink the water-like fluid that has infected the city's water supply and it is irreversible. At the same time, Elena learns of the APO team's arrival and sends Sloane and her men to go out to kill them, leading to a three-way ... Written by Anonymous

A great season finale with shock in the final seconds!
22 September 2010 | by (United Kingdom) – See all my reviews

This episode begins where the last concluded; the team arrive in the Russian city of Sovogda and find that there is something very wrong with the population. They have been infected by a waterborne agent and this has been activated by the Rambaldi device. The effect is that they become uncontrollably violent and behave in a similar way to those infected in the film '28 Days Later' their presence will make it much more difficult for the APO team to get to the building where Elena has set up the device. They manage to get there by using an underground train but in the process Nadia is left behind and it looks as if the infected hoard have killed her. As the train arrives at its destination they find Sloane waiting for them along with several dead soldiers; he claims to have been working to bring down Elena the whole time and is soon helping them capture her. When Sydney goes to deactivate the machine she makes a shocking discovery; Nadia survived the hoards but was captured and infected by Elena; if she wants to deactivate the device she may have to kill her own sister! While all this is going on in Russia Marshall and Weiss are struggling to hack in to the Russian satellite system; it was a good job Sloane had kept a copy of the Covenant's 'blackmail list' as it enabled them to get the password from a Russian minister. The neutralising of the device isn't the end of the episode though; we get what appears to be a cheerful epilogue Sydney and Vaughn discuss their wedding plans then in the last couple of seconds we are hit by a double-whammy that I won't spoil here.

This was an exciting conclusion to the series with some nice twists; it was pleasing to see that Sloane had managed to remain one of the good guys after all even if his actions were unauthorised. I hope that Nadia can be cured early in the next series as she was a welcome addition to the team; Mía Maestro was very good in the role making Nadia a strong character with a hint of fragility that her older sister does not have. While the action scenes were fine the most fun was seeing Marshall and Weiss blackmailing the Russian minister; we aren't shown what they know about him but it is clearly rather perverse. After the dark scenes in Russia the epilogue seemed light and breezy till the last seconds which set up what is bound to be one of the main stories of the fifth and final season.
