In the real world, cell phones have become almost indispensable. And in the movie world of the new thriller "Cellular" (search), Kim Basinger's (search) life depends on one.

Directed by David R. Ellis, the film follows the story of a kidnapping victim who must convince a total stranger on the other end of the line to help save her life. Jessica Martin (Basinger) makes a random call and ends up connected to a young man named Ryan, played by Chris Evans (search).

Jessica tells the cell phone owner she’s been abducted and thinks she’s going to be killed soon. She begs him to help save her husband and young son, whom the kidnappers have gone after next.

But Ryan doesn’t have an easy task ahead of him if he decides to save the day. His battery is low and could die at any minute – and the frightened victim has no idea where she or the rest of her family are.

“The thing I actually loved about it was [that] it was a ride I could take with the audience,” Basinger said of the movie.

Evans said “Cellular” is an adrenaline rush and manages to sustain that anticipation throughout.

“It’s one of those movies that’s just fast-paced,” he said. “It remains up there for the whole film. There are moments of comedy and drama, but it's all a byproduct of the suspense.”

It’s also a flick that takes the importance of the cell phone to a whole new level, making it a literal lifeline for Basinger’s character.

“They’re a very important tool,” director Ellis said. “At the same time, I think they’re abused. I hate them in restaurants, I hate them in movie theaters, I hate it when people are not paying attention as they’re driving down the road.”

“Cellular,” rated PG-13, opens this weekend.
