It is a strange and cruel world that Amelia finds herself in. The 17-year-old woman from Mexico who speaks very little English travels to Oakland, California to marry her boyfriend Manolo. Soon after, he is sentenced to 8 years in prison. Amelia is already pregnant. She and her newborn son, Jesus Romero, move in with Manolo's aunt and uncle. Amelia refers to the baby as "mijito" (an affectionate Spanish term for "little son"). He cries constantly and has a hernia that requires repair. But the teenage mother is overwhelmed and frightened. She receives little support.

Amelia and Jesus go to the Oakland Children's Hospital where they meet a cynical but kind nurse who works with a group of 6 pediatric surgeons. Most of the surgical practice consists of Medi-Cal welfare patients and lots of illegal aliens. The nurse encounters crack babies, kids with AIDS, and plenty of disabled children. When the surgeon examines Jesus, he notes bruises on the baby's arms. They are the result of Amelia squeezing him too hard to stifle his incessant crying. Surgery is scheduled but doesn't get done.

Later, the uncle makes sexual advances and, while drunk, rapes Amelia in the bathroom. The aunt insists Amelia and Jesus leave the apartment. She deposits them at a homeless shelter. Amelia spends her days riding buses and her nights at the shelter where she is harassed and robbed. All the while, Jesus cries. Amelia notices his hernia is protruding and she is unable to push it back in place as she was instructed. After office hours, the same nurse evaluates the situation and accompanies them to the emergency room where surgery is performed.

Amelia and Jesus return to the ER. She has been sedated and is staring blankly. Jesus is dead with a broken neck. The nurse from the surgical clinic is at Amelia's side and learns that Jesus was crying in the homeless shelter and keeping others there awake. Amelia shook the infant to try to quell the crying. She didn't know what else to do.
