She's a Keeper/Walkthrough

The following is a walkthrough for the mission She's a Keeper in Grand Theft Auto IV.

Get into the car with Gracie. During the ride, the Ancelottis are chasing Niko with guns blazing. This mission requires some finesse behind the wheel; If Niko drives too recklessly, Gracie will break her neck and the mission fails. If Niko drives too slowly, the Ancelottis will accidentally shoot her and the mission fails. During the mission, Niko can hear Gracie screaming in the trunk. If she stops screaming, she may be dead. Drive carefully to the new safehouse (note: you're home free once you hear Niko say "we're keeping this bitch", meaning you've lost the pursuers). An alternate starting route allows Niko to get a head start on the Ancelottis. To use this shortcut, take a dirt road on the left, just past the garages, as Niko starts out. This shortcut will allow Niko to arrive at the freeway before the Ancelottis, and avoid the majority of the pursuing cars. After Niko and Gracie safely arrive at the new safehouse, Packie comes out to get the car, and the mission is complete.
