CJ is on his way back to Los Santos from Liberty City, after he received a call that his mother had been killed in a drive-by. As CJ makes his way from the airport, the cab he is in is stopped by some police officers. You'll meet 3 corrupt officers known as Frank Tenpenny, Eddie Pulaski and Hernandez. They link you to a recent killing of a cop and escort him into Ballas territory (rival gang to CJ's Grove Street Families). They dump you in an alley with nothing but $350 in your pocket and no weapons.
Approach the BMX bike with the marker and jump on it with the Triangle button. Follow the roads leading to the "CJ" marker on the map. When you reach your destination, you find yourself in the old neighborhood. Enter the red marker to begin the first true mission.
CJ picks up a picture and starts reminiscing about his family. Big Smoke comes in, with a bat, and thinks that CJ is a burglar. CJ reminds Smoke of who he is and they start talking. Smoke says they will visit the gravesite, where CJ's brother and sister are.
SWEET & KENDL
REWARDS - BMX Challenge unlocks, Respect
When you get to the gravesite, you're greeted with a hug from your sister, Kendl. It doesn't take long though for some family problems to take over and some arguing ensues. Kendl leaves to go see her boyfriend Cesar, whom Sweet doesn't like.
As it looks like you're about to leave, some Ballas drive by and start shooting at you, with them blowing up Smoke's car. You'll have to hop on a bike and keep close to Sweet. Sweet is represented by a blue marker on your map and you can see a blue triangle above his head when you're close enough. A Ballas car will be following you, trying to shoot at you in the process. If you're getting hit, brake and then try to get past the car. Eventually, you'll stop in a clearing and Sweet will split from you to draw away the Ballas. After this, you'll have to follow Ryder now back to the cul-de-sac where your house is. Mission done and some respect earned.
Completing Sweet & Kendl will open up the BMX Challenge.
Go inside your house to continue and save once you're inside by stepping onto the disk in the kitchen. After you're done inside, go back outside, walk a bit and your cell phone will ring. Ryder will explain a bit of the situation right now in the neighborhood. Once the conversation is done, step inside the red marker nearby to start the next mission. It is in front of Ryder's house.
REWARD - Respect
Get inside Ryder's car and head towards the yellow marker on the map. Once there, get out of the car and enter the barber shop. Step in the marker inside and you'll get a list of haircuts. Pick anyone you want and go back outside. Ryder will comment on the haircut and will tell you to enter the pizza shop across the street to get some food. Enter the building, walk to the counter and order some food. After you eat it, Ryder will walk up to the counter and hold up the place. The clerk behind the counter will pull out a shotgun and begin firing at you. Once outside, get into Ryder's car and drive him to his house; you can also drive over the pizza employee, who will drop the shotgun if killed. He tells you to go and see Sweet next.
