Friday's episode of CSI: NY may feature a side of Mac Taylor viewers don't see very often.

The episode— the conclusion of the CSI crossover event that began on the mothership series Wednesday — finds Mac (Gary Sinise) and D.B. Russell (CSI star Ted Danson) returning to New York to track down the people who have kidnapped Mac's girlfriend Christine (Megan Dodds). And given Mac's personal investment in this case, his desire for justice burns even hotter than usual.
