Friday Night Preview 05.05.06

TGIF. Its Friday and May sweeps are in full effect with the season finale of Ghost Whisperer and new episodes of Numbers and Las Vegas.

Ghost Whisperer – 8 pm/ET, CBS (Season Finale)

Melinda has her hands full tonight in the first-season finale when she is inundated with requests for help after a plane crash. The spirits of hundreds of victims want to know what happened — and so does the government. The situation is complicated even further by a menacing entity who tries to keep the souls from crossing over. Melinda ends up getting help from a surprising source, but the real shocker is saved for the last five minutes.

Las Vegas – 9 pm/ET, NBC

The neon-bright Sin City series has had its share of cameos this season, and the trend continues tonight when Olympic figure skater Sasha Cohen makes an appearance. Elsewhere in the episode, Delinda answers Dr. Derek’s marriage proposal, and Danny and Mike investigate a couple of high rollers’ claims that their spouses are cheating.

Numbers – 10 pm/ET, CBS

Don is used to tracking bad guys who have committed crimes against others. But tonight, Don fears that he and his family may be the targets after his checking and savings accounts are cleaned out by computer hackers. The probe leads to some nasty crooks connected to the Russian mob.
