This job is for Fumo, and you are required to actually help the police for a change. Essentially, the want to improve their PR image by holding a fake drugs bust. We just need to get them the drugs they need for it. Go and meet Narco at the location on your map. You will then have to get into his van and drive to the location indicated with the drugs.
Once you get there, it will in fact be a Disciple ambush awaiting you. This bit is very tricky. The game states that you need to protect Narco and the angel dust, but it is nearly impossible to stay in the area and do that. We advise you drive off to a safe distance, get out of the van (leaving Narco and the drugs inside) and head back to deal with the police on foot. Once you have mopped them all up (some may remain in their vehicles), the game will jump to a cut scene with Narco and Angel in a boat, so there is certainly no harm in leaving him in the van in a safe spot.
Once you are in the boat, you have to protect it from the Disciples. Fire out of the back of the boat at the few speedboats who chase you. It shouldn't be too difficult to despatch them. You will also have to contend with foot soldiers and jet skis, but before too long the game cuts to Narco being shot while driving the boat. You must take over.
