The Boy Who Harnessed the Wind (2019) Plot Summary & Ending Explained

William was expelled from school because his family couldn't afford to pay his tuition fees. Despite being a bright student who loved learning, the financial burden of school costs became too much for his family to bear during the difficult economic conditions in their village.

Foreshadowing: This expulsion sets the stage for William's self-directed learning journey in the library.

William leveraged his sister secretly dating science teacher Mike Kachigunda. He asked Kachigunda to let him continue attending classes and using the school library, which allowed him to study electrical engineering and energy production on his own.

Foreshadowing: His access to the library becomes crucial for researching wind energy.

The severe drought destroyed all crops in Wimbe, leaving families without food. With no harvest to eat or sell, the village faced starvation. The government's rationing system couldn't support everyone, leading to riots and further chaos.

Foreshadowing: The drought is introduced early as an inevitable force the community must face.

William's sister chose to elope with Kachigunda to reduce the family's burden during the famine. With food supplies already stolen and starvation looming, one less person to feed helped the family survive the crisis.

Foreshadowing: Her departure is signaled by the increasing desperation in the village.

William's father, Trywell, dismissed the windmill idea as a waste of time and effort. With the family struggling to survive the famine, he believed William should focus on manual farm labor rather than chasing what seemed like an impossible dream. In his frustration, he destroyed the prototype.

Foreshadowing: Earlier scenes show Trywell's skepticism toward Western ideas and his focus on traditional farming.

Khamba died from starvation, just like many other animals and people in the village during the famine. The severe food shortage affected all living creatures, and the loyal dog succumbed to the harsh conditions.

Foreshadowing: Earlier scenes show the family's diminishing food portions, hinting at the dog's fate.

William's mother, Agnes, intervened after Khamba's death, urging Trywell to reconsider his stance. She recognized William's determination and believed in his vision. After the emotional moment of burying Khamba, she helped facilitate reconciliation between father and son.

William used the chain and sprocket from Kachigunda's bicycle (which his sister left behind after eloping) as the core mechanical component. This part connected the windmill's blades to the generator, allowing the rotational energy to be converted into electrical power.

Foreshadowing: William specifically requested this component from his sister before she left.

The windmill generated electricity that powered the village's dormant water pump. This allowed farmers to draw water from underground sources and irrigate their fields, bypassing the failed rains and enabling crops to grow despite the ongoing drought.

Foreshadowing: William's initial research in the library focused on how wind energy could generate electricity.

• electricity
• irrigation
• drought solution

The construction succeeded because William gained his father's approval and the entire community's support. With more hands helping and resources from the salvaged bicycle parts combined with salvaged materials, they could build a full-sized version that worked.

Foreshadowing: William's mother played a key role in changing his father's mind.

• community
• construction
• teamwork
• collaboration
• success

The windmill ended the famine by enabling irrigation and a bountiful harvest. It restored hope to a community that had been facing starvation and displacement. The success demonstrated that ingenuity and perseverance could overcome seemingly hopeless situations.

Foreshadowing: The narrative builds toward this moment as the culmination of William's journey.
