I just watched it.
At first, I was reluctant and I said "What kind of title is that?!!?"
But the movie turned out to be excellent. It's about a kidnap. Kim Basinger played as a kidnap victim, mother of one, wife of a property agent.
The only accessible phone where she was locked up was shuttled by the kidnapper. She tried to dial out by connecting the broken wires and randomly called a young man Ryan who was on the road. She pleaded the young man to save her and her family whom the kidnapper was going to kill eventually.
With no knowledge of Jessica Martin (Kim Basinger) other than her hushed, panicked voice on the other end of the tenuous cell phone connection, Ryan (Chris Evans) is quickly thrown into a world of deception and murder on his frantic search to find and save her. Jessica's life is in his hands, but what is waiting for him on the other side of the line, and what will it cost him to find out?
