Gehlaur, Bihar, India. 1960.
A poor farm laborer named Dashrath Manjhi climbs the rocky mountain outside his village. In his hands are a hammer and a chisel.
He sets the chisel against the stone and swings.
The mountain stands between his village and the nearest town. Going around it means a trip of about 55 kilometers (34 miles). Going over it means a narrow, dangerous path across the ridge.
Manjhi has decided there will be a third way. He is going to cut a road straight through the rock, by himself.
He is not an engineer or a stonecutter. He has no machines and no money. Soon, people will be calling him a lunatic.
He has a reason to keep going anyway. It has to do with his wife, Falguni, and with that narrow path over the ridge.
He will keep at it, day and night, for the next 22 years.
