La Femme Nikita Pearl, 10.30pm The intensity of the personal story of Michael (French Canadian actor Roy Dupuis) reaches its climax this week, with the sexy agent-cum-father driven close to suicide. With arch terrorist Vacek now eliminated, so too is Michael's 'normal' family life outside Section One. The huge personal sacrifices the agent has shouldered are, not surprisingly, too much for him. But of course, there is still Nikita (Australian-born Peta Wilson, above). When her life is at risk he has to consider once again if there is anything worth living for. Seinfeld Pearl, 9pm This is the first of a two-part special, called the Bottle Deposit, in which Elaine (Julia Louis Dreyfus) is sent to an auction to bid for a set of J F Kennedy's old golf clubs and pays over the odds for them. Jerry, meanwhile, manages to lose the precious bag. Kramer and Newman come up with a scam to make money from used bottles and George gets into trouble when he fails to follow his boss into the men's room, and misses hearing an all-important instruction. Chicago Hope World, 9pm With his new medical team now established, David E Kelley's series gets back to the nitty-gritty of emergency room cases. In this episode, Dr McNeil gets the saw out when a young baseball player has to have his arm amputated, action which results in the hospital being sued. There is, though, the usual quirky twist, in this case involving horse manure. The New Edge Pearl, 8.30pm A special episode on space, with a report on the International Space Station Programme. Each of the 15 countries involved have been developing separate pieces of hardware, ready for the assembly, now underway, in space. The reusable Rotary Rocket, which can launch both payloads and people at a fraction of the cost of today's systems, is also featured. A Microlight Odyssey National Geographic, 9pm Colin Bodhill, who was brought down by the Chinese airforce recently, is not the first to attempt to circumnavigate the world in a microlight aircraft. Two years before his escapade, British pilots Brian Milton (above left) and Keith Reynolds (right) set out to trace the famous 80-day journey of Jules Vernes' fictional characters Phileas Fogg and Passepartout and be the first to complete the feat. Their adventure can now be followed in a four-part series starting tonight. This episode takes them over the Alps, the Mediterranean and the Saudi Arabian desert. The views will be spectacular, but the two pilots faced many a mechanical difficulty along the way. Also, five of their 80-day target was wasted waiting in Hanoi for permission to fly over China, which they did before touching down en route in Hong Kong. Drinker's Dilemma National Geographic, 8pm This film has nothing to do with the pros and cons of enjoying an extra beer or two in the pub, but the risks a beast must take to quench its thirst at an African waterhole. Complex relationships between the animals who frequent a waterhole are explored.
