can someone please explain what happens in this story? The images are too much for me but words are okay + i'm very curious

So Brandon saved Andy from train and because of that, Bran got injured and epilepsy. Because andy felt indebted to bran, he took care of him. Andy is mentally ill so he's being a killer (mostly kill people who connected with brandon). Two of brandon's friends killed by andy, but poljce suspected bran's the one who killed them so they investigated him. Then andy took bran/kidnap and abused him. The detective who suspicious about bran who's missing went to andy's. And andy killed the detective then took a trip with bran. but bran tried to get away and asked police for help. instead of got a help, the police shot bran. andy got mad and killed the police then bran+andy fell to train's. bran thought andy's died but a year later he came again for him
darn, why do I feel so defeated?
