This is the final Gianna mission and the final job in Gangstar Rio. Gianna has finally managed to build a case file against the DICS and is blackmailing them for millions. She needs to leave town before they send more hitmen after her. We need to get her a plane, so head for the airport.
Once you arrive there you'll have to take out the two police officers guarding the area, then you'll need to head to the DICS warehouse. You can run to the next objective waypoint, or drive there. But once there you will have to fight your way to the plane. There will be two DICS officers outside, two more inside the warehouse, then two more on the docks by the seaplane.
Get in the plane (dealing with the DICS officers shouldn't be too hard). Two boats will arrive as you near the plane - you can either take them out or get in straight away and make your escape. Once airborne, you need to make your way to Gianna. Landing is easy as you can set down on the lake, then just move slowly to get to the objective arrow. Once there, Gianna takes over and the mission ends. She will be heading to Mexico, apparently to start a drug's cartel. Whatever her future plans, she's very grateful for all Angel's help.
