SD-6 learns that Sark is planning to launch a satellite - and Sydney learns from her mother what he's looking for: a music box designed by Rambaldi that contains an encoded mathematical equation for a new type of energy. So she's sent to Sri Lanka to plant a device on the satellite to enable SD-6 (and the CIA) to locate the box and get it before Sark does. Not a classic episode by any means, but it does execute some ambitious action scenarios and contains a particularly gripping "hypnotizing" sequence with a CIA specialist trying to get Will to remember the codes for activating the music box as they were written on Sark's computer on the plane that was taking them to Taipei. Though the best scenes of the episode are, as with the previous one, those with Irina - she meets not only Sydney but Jack as well. Lena Olin has a great physique - you can see where Sydney got her on-screen good genes from! *** out of 4.
