Grand Theft Auto 4: The Ballad of Gay Tony Guide - Walkthrough
Tony's Missions - Mission 10: Ladies' Night
Follow the marker on your radar to the helipad on top of the Booth Tunnel exit. There, get out of the car, hop into the helicopter, and wait for Tony to get in as well. Fly over to the marker in Meadows Park to spot the suspected kidnapper.
Once you've spotted the kidnapper, it's just a matter of following his red car. Unfortunately the target is not marked on your radar, so it can be easy to lose track of him. However if you hold the B button the camera will focus on him. So if you lose track of him, hold the B button and fly in the direction it points to.
Keep track of the red car as you fly overhead.
To satisfy the “Close Pursuit” and “Low Fly” secondary objectives you must remain close to the kidnapper during the entire mission and not fly too high up. How low you're supposed to fly is not clear.
When the kidnapper enters a tunnel, hold the B button to keep track of him.
The target will eventually reach a building in Westdyke, Alderney. When he stops there, fly to the marked helipad in Alderney City and land the helicopter to complete the mission.
