A power cut will lead Mac and Stella into the world of extreme sports in the upcoming episode "Tri-Borough" when it turns out the victim was a real-life spider-man, CSI Files sources revealed today.

In a huge city like New York, local power outages are not an infrequent occurrence, and usually don't require more police involvement than a patrol car taking an extra cruise through the neighbourhood to check everything's still peaceful. So what are Mac and Stella doing in this regular Queens neighbourhood, where all the power went down during last night's Knicks game? Unlike most power outages, this one was caused by a young man being electrocuted.

As the CSIs find that somebody tried to dispose of the body, they realise this probably wasn't an accident, and the man was murdered. Unfortunately, none of the neighbours are able to provide them with any information, and without further evidence, Mac and Stella are unable to enter any of the houses. Rather than try and find out more about the killer, they set about uncovering the identity of the victim. Eventually, they discover his name was Red Hontz, nickname 'Slick,' and last night, he was Parkouring.

Parkour is a new extreme sport that was invented in the late eighties by Frenchman David Belle. Athletes who practise the sport see the city as an urban obstacle course, climbing on rooftops, jumping from building to building, and performing somersaults and flips to make their "parkour run" even more spectacular. No deaths have yet been reported among participants of the sport, known as traceurs, but bruises and broken bones are not unheard of after some of the most death-defying runs.

But for Mac and Stella, it's not the thrill that counts - it's the sport's potential for criminal abuse. When you're scaling skyscrapers and sliding down firescapes, what do you do when you see an open jewelry box behind a window on the eleventh floor? In fact, Slick's best friend, and the last person to see him alive, is a traceur with a burglarly conviction on his record. Could Slick's death have been the result of another less than legal diversion from his parkour run?

While Mac and Stella delve into the world of extreme sports, the rest of the CSI team is kept busy with two other murder cases. Danny takes along a Detective Maka to investigate the death of an art dealer who appears to have been involved with a major scam involving fake paintings. And after Mac and Danny's encounter with construction worker unions in "A Man A Mile," it's now Aiden's turn, as she is assigned to the case of a workman found dead at a construction site.

"Tri-Borough" will likely air sometime in early December. Please note that this plot information has not been confirmed by CBS or Bruckheimer TV and until such time you should treat it as you would any other rumour from an unofficial source. The details are based on an early draft of the script and aspects of the episode may change before it goes to air.
