That's Taken in a nutshell.
Liam Neeson plays a father whose daughter is kidnapped by human smugglers in Paris. It's a nearly 2 hour thrill ride, with a little intrigue, a little detective work, and a whole of dead bad guys.
Neeson plays Bryan Mills, a former CIA operative that is trying to get to know his estranged daughter, Kim , played by Maggie Grace. Kim goes with her friend, Amanda, to Paris for the first leg of a European tour. They meet what they believe to be a fellow traveler, Peter, at the airport, and share a cab with him. He turns out to be the spotter for the white slavery ring, and soon after a couple of thugs break into the apartment the girls are staying at and kidnap them.
Bryan goes to Paris and begins to look for Kim, using all of the skills that he learned in the CIA. He confronts the kidnappers, and proceeds to kill them, keeping one alive to gain information from in a rather unique way. He finds out that Kim has been sold to a broker of girls that caters to rich Arabs, so he infiltrates the party/auction where the girls are being sold. He sees her on the block, and forces one of the guys to keep bidding to win her.
As he tries to leave, he's attacked by the broker's thugs, who try to kill him. He puts the beatdown on these guys, and kills the broker before going after his daughter, who is in the hands of the Arabs. There's the obligatory chase through the streets of Paris along the Seine, and Bryan jumps from one of the bridges onto the Arab's boat, where he proceeds to kill everyone onboard to get Kim back.
I've left out some stuff to get you to actually go and see the movie, which you had better do.
