When the family returns to the townhouse, Abed lets loose.

"Plastic surgery? Plastic surgery? We came all the way here for a cosmetic surgery that won't fix anything?" he testily asks Khan, the human rights lawyer.

Khan ponders for a minute what to say. What can possibly make up for a father's dashed expectations?

"Have faith in God," she finally says. "God has grand designs for your son."

A trial awaits

Back home, a difficult trial awaits -- one in which Okkhoy will eventually have to take the stand and relive, second by excruciating second, what was done to him.

"We hope that there will be some appropriate punishment," says Sohail, the battalion commander. "An exemplary punishment for these criminals so that the rest of the country knows."

The gang, according to battalion officials, has maimed at least five other children -- all of them around Okkhoy's age.

One of the men who confessed told investigators how the gang kept the kids confined for months in tight spaces or even in barrels and deprived them of food.

Then they'd send them out to beg.

Each child would bring back the equivalent of about $7 a day. The gang kept all but 25 cents of each haul.

The kids received mere pennies to feed themselves.

Were it not for Okkhoy, the enterprise would carry on.

"He's the only witness, the only witness who saw everything with his own eyes," Sohail says. "Without his statement, without him testifying in court, the case cannot be won."

Okkhoy's testimony is crucial for another reason.

The battalion has a reputation for coercing confessions, and human rights groups have long accused it of heavy-handedness in dispensing justice.

The U.S. State Department's latest report on human rights in Bangladesh accuse the battalion of using "unwarranted lethal force," and the government of withholding figures on how many extrajudicial killings it has committed.

Sohail, the battalion commander, sees it differently.

"The human rights activists and our style of work may be different but the goal is the same: to protect the human rights of innocent victims," he says.

The big day

It's the morning of the surgery, and Okkhoy is up before the sun. If he's nervous, he doesn't show it.

He makes faces at the staff, and tries to impress them with the English he's learned since arriving six days ago. "1, 2, 3, 4," he counts, holding up his fingers.

It amazes everyone who meets him.

"For a boy who's been through this kind of trauma, and seen this many doctors, I can't believe he's not scared of hospitals, he's not scared of doctors," Gearhart says.

As he is wheeled into the operating room, Okkhoy flashes a thumbs up.
