You can call on the characters from one television show to attempt a rescue.
Which show do you pick?
Me: I'm going to go with Arrow. They have a big team, cops on their side, ex military, a tech person, a fairly high success rate of rescuing people... and have managed to even bring some of them literally back from the dead, so yeah...
24, because Jack Bauer's methods always works well at least he rarely ever fails, and that is as long as he's well coordinated with Chloe O'Brien, and also because he doesn't hold anything back. He does whatever it takes ensure the Full Cooperation of any conspirators or all those that are in on any conspiracy such as "kidnapping".
Do I have to pick only one show?
If not then, I'd also go with SuperNatural's Winchester brothers, because they also have a powerful allies such as Castiel and Crowley. But if I ever get rescued I'd keep away afterwards, don't want to hang around them and end up like Kevin or Charlie did.
