the heroine is secretly an amnesiac and brainwashed 'superspy'
scene in which the heroine straps knives to her feet and ice skates through a pool of liquid petroleum in order to murder her way through twenty goons.

They're channeling The Long Kiss Goodnight so hard, though there amnesiac 'superspy' Charlie straps ice skates to her feet to skate across the lake and uses a pistol to kill the three bad guys chasing her friend's car. Oddly enough that also features Samuel L Jackson, this time as the world weary private eye she hires to figure out who she is.
