The mission can begin with or without a cutscene--if the player transfers to Franklin at a point when the mission is available but not yet officially started, the mission may simply begin without the player seeing a cut scene between Michael and Trevor at Trevor's trailer. Regardless, once the mission commences, the player takes control of Franklin and Chop in a Baller as they pursue the remaining O'Neil brothers who are in a Dubsta. Franklin calls Trevor and informs him that he is following the O'Neil brothers along the Great Ocean Highway near North Chumash. Trevor informs Franklin that he and Michael are coming to Franklin's position.
The O'Neil brothers soon drive into Raton Canyon, with Franklin still in pursuit. A doe steps into the O'Neil's path and they swerve to miss it, causing their car to crash. Franklin, with Chop in tow, exits his Baller and goes to the crash site, only to discover that the O'Neils have disappeared into the woods.
At this point, the player is shifted to Trevor. Trevor and Michael arrive at Sandy Shores Airfield and board Trevor's Frogger. They fly to Franklin's location. Once there, the player is shifted to Michael, who uses a sniper rifle with thermal scope to kill the O'Neils, a task complicated by the fact that the area is swarming with deer whose thermal signatures are similar to that of the O'Neils. Michael eventually kills two of the brothers, but then Elwood O'Neil starts shooting rockets at the helicopter, forcing Michael to abort.
The player is shifted back to Franklin, who is still on the ground with Chop. Trevor tells Franklin to find the remaining O'Neil. The player is then prompted to shift to Chop, who tracks down Elwood. Franklin follows Chop and kills the remaining troublemaker. The player is shifted back to Trevor who lands the Frogger so that Franklin and Chop can board. The group flies back to Sand Shores Airfield.
