Like the first Sin City film, this one is made up of sub-stories that, in some way or another, tie in to the main plot.
Just Another Saturday Night:
Marv (Mickey Rourke) is thrown from a vehicle. He has no idea how he got there or what just happened. There's a dead body lying near him. He grabs his pills and pops several into his mouth.
He recalls walking through the projects of Basin City, an area where he was born and raised. As it was a Saturday night, Marv remembers being at Kadie's, getting drunk and checking out stripper Nancy Callahan (Jessica Alba), along with all the other men in the joint. Outside, Marv sees a man on fire running and screaming. He comes across four preppy college boys dousing another man with gasoline. Marv breaks a bottle in front of them and tells them to let the guy go. One of the boys pulls out a gun and calls Marv a "Bernini Boy", but Marv thinks he called him "Bernie". He shoots Marv in the shoulder. Marv is mostly unfazed and when he doesn't go down, the boys get frightened and run. Marv catches two of them on the rooftops, aiming their guns at him. Two arrows come down, and Marv knows who's near. He makes a gesture to show he's on their side, and then points at the boys. Two more arrows hit them. Marv meets the two boys and asks the one that shot him why he called him Bernie. The boy says Bernini is the maker of the coat Marv is wearing. Marv then calls for a knife and slashes the boy's throat, while the other one takes another arrow. Marv then hijacks a cop car and chases after the other two, ramming into their car and bringing him to where we found him. He steps on the last boy's chest and crushes his lungs before lighting up the gas and blowing the cars up and fleeing the scene.
