The side kick didn't connect well enough as Winter Soldier showed an almost freakish speed.  As his metal arm deflected the blow, Cap was exposed as Winter Soldier grasped her.  Clinging her against the metal railing Cap had to struggle to get an arm exposed to try and fight back.  He back arching over the cold metal as Cap felt her right leg leaving the ground.  She reared it back and used it to hit kickboxing style knees at Winter Soldier's kidney.  None of the strikes through seemed to make any difference though.  Winter Soldier's eyes and whatever else of his face she could see was cold and dead to everything.

Finally as she felt her right arm loosen she grasped and grabbed Winter Soldier's normal arm.  Pulling it in and got her legs up, tightening them around his shoulders as she let herself slip over the railing.  Pulling Winter Soldier's arm into a cross arm breaker while she hanged over the balcony.  Gritting her teeth and trying to subdue him, or at least put him in a severe handicap if the fight keeps going.
