Life is not an action movie. If that actually happened I wouldn't be blindly throwing myself in the middle of a group of armed/dangerous guys. I'd be calling the cops (they're more trained than I am to handle the situation) and freak out hoping nothing bad happens to her.
In America you just stop by the next gas station and buy a ton of explosives and a machine gun with 30 filled magazines. Then you grab a jerrycan of gasoline and some lighters and the cashier wishes you a nice evening on your party.
Nah, I'm my fantasies I go Rambo style and slice everyone with a tactical knife while wearing a ghillie suit and warpaint, before carrying my wife victoriously in my arms to safety...but that wasn't the point was it ?
