(CNN) - A flaring furnace blasts another wave of searing heat on the faces of workers hauling bricks under a southern Indian sun.
They work up to 22 hours a day propping heavy stacks of bricks on their heads. None expects to be paid for this labor. None knows how long they'll be kept here. Some are as young as three years old.
Manoj Singh was one of 149 people rescued this year from a brick kiln outside Hyderabad, India. Like millions of other Indians, the toddler was born into extreme poverty.
When CNN correspondent Mallika Kapur visited Manoj's family, now back home, he and the some of the 34 other children freed, showed her how they would make the bricks from wet clay.
"They recall from their muscle memory," says Anu George Canjanathoppil, of International Justice Mission, a non-profit dedicated to eradicating slavery around the world. "So if you ask them to explain what they did, they cannot say."
Older laborers, however, had plenty to say. FULL POST
Editor's note: In some Indian villages, girls are sent into prostitution by their families - a tradition that began as religious obligation but is now continued for money. In "Trapped by Tradition," which airs Saturday and Sunday on CNN International, (viewing times below) "Slumdog Millionaire" star Anil Kapoor shows how Indian charities are trying to stop the tradition. CNN has changed Priya and Meena's names.

Bharatpur District, India - Leaving home at 5 a.m. for a shoot is nothing unusual for me but this trip was definitely very different - a road trip from Delhi to a village close to Bharatpur in Rajasthan to talk with working and former prostitutes.
As a Plan India Patron and Goodwill Ambassador I visited this village two years ago. I was looking forward to this trip because I am an optimist and was keen to see the change that has taken place here.
India has traditionally been a patriarchal society and unfortunately the rate of female infanticides is quiet high. In this village, families rejoice on the birth of a girl child - but for the wrong reasons.
The reason behind celebrating a girl's birth in this area is a dark one. Some members of this community practice a caste-based sex trade - and have done so for generations.
The men knowingly send their own daughters and sisters into the sex trade.
I was anxious to see what milestones we had reached in trying to stop this tradition - this time visiting with CNN International's Freedom Project initiative to fight modern day slavery.
We received a warm, ceremonial welcome at the village and were greeted by a group of young girls singing. I was struck by the words as they sang: "Give our daughters respect too."
Being a father of two daughters, it got me thinking, if we don't empower our women, how would our families progress?
I had the opportunity to share my thoughts with the women of the community. I sat down with some who had been forced into the sex trade by their families. Some of them were rehabilitated with help from Plan India and Gram Niyojan Kendra, a partner charity working in the same field, while some were still working.
Their stories gradually came out. They told me of their misery, the horrid tales of being sold in their teenage years, of becoming bread winners for their families.
I must confess; the few hours spent with these women were really difficult. At times, I wouldn’t know how to react - console them, cry or get angry with a system as inhumane as this.
With a sigh, Meena remembered the blissful day when she came back and was rehabilitated with Plan India's help. With a radiant spark in her eyes, she said: "I bought a buffalo with the help of Plan and GNK and now I sell milk and milk products in my village."
Meena has promised herself that her daughter will go to school and not suffer like she did.
Priya was also in the village that day. She's a sex worker in Delhi and sends money home to support her family. Her elder sister, in her late 40s, has left the trade because of her growing age.
It's very difficult to get women Priya's age, - she's in her mid-30s - who are already working as prostitutes, to quit because they get used to the income. That's why Plan India focuses on children, working to prevent them from entering the trade to start with.
Priya believes she has no choice. She says she must continue working as she has a large family to support. She has to feed her children and she's supporting her sister-in-law and her children too.
She says that things are changing for the younger girls, thanks to all the money women from her generation have earned for their families.
But she also appears torn at times, sometimes defending the prostitution, sometimes directing anger at her family.
She said: "When I told my elder brother to put his daughter into the trade, he broke all ties with me and moved out.
"I made the marriage of both of my brothers possible and even today I am taking care of my younger brother’s family because he passed away recently. No one has ever acknowledged the value of sacrifices made by me and my sister."
It was time for me to talk to the male members of the community. As always, most of them were initially in a denial mode but started to open up gradually.
They reassured me that in last four years with Plan India and GNK's efforts, a lot of the women have been pulled out of the sex trade and more families are now determined not to push their girls into it.
Also, a lot of the rehabilitated women are ensuring that the girls from their families don’t get thrown into the practice.
It's a small step, but one in the right direction. Changing the mindset of the people in the village is key.
Now that the women themselves are taking a stand against prostitution, I am hopeful, optimistic we can end this tradition.

In "Trapped by Tradition," which airs Saturday and Sunday on CNN International, (viewing times below) "Slumdog Millionaire" star Anil Kapoor shows how Indian charities are trying to stop the tradition. CNN has changed Priya and Puja's names.
Bharatpur District, India - She's around 13 years old. She goes to school, loves to sing and dance, and between giggles, she says she dreams of being an actress one day.
Puja hardly looks like a fighter but beneath her smiling face is a steely resolve. She is the first girl in her family to go to school and is determined to finish it. Very few girls in her community have done that.
Puja's mother wasn't given that chance. Priya, now in her late 30s, was forced into prostitution when she was a young girl.

Chennai, India - Beaten with rods, belts and subjected to other forms of abuse, the bonded laborers toiled away in a tiny brick kiln in southern India day after day with little hope of freedom and escape.
But on a tip, officials from the government of Tamil Nadu state in India raided the kiln. What they found shocked them: More than 500 people living and working under a brutal and oppressive system.
"We worked all the time. We would only stop to eat," says 20-year-old Dambru Jani, who was rescued in the raid. "If we tried to rest, they'd abuse us and force us to work again." FULL POST
