Inside story on fall of Gaddafi's brutal regime

While in London watching "shocking news footage coming out of Libya", the Libyan diaspora were faced with a question: what role would they play in the Libyan uprising?

So said Ibrahim El Mayet, 30, one of thousands of Libyans around the world who joined the struggle against Muammar Gaddafi's regime.

Gaddafi's leadership was overthrown on August 23 and he died on October 20.

"Many returned to Libya to join the opposition. Libyans were offering their skills, resources, energy and lives in the struggle for freedom," he said.

El Mayet helped establish a radio station. He also set up training camps in the mountain towns of Jadu and Kikla. He and his father, Abduladim, bought two ambulances, which were loaded with medical supplies, and they decided to travel to affected areas.

On their journey back to Libya they were joined by producer and director Anne Reevell and executive producer Jon Blair.

The result of filming this journey is a documentary series titled Gaddafi: The End Game, which tells the inside story of the fall of a brutal regime.

"I was able to film with a small group of Libyans from the UK. As the months passed, their determination transformed them into revolutionaries," Reevell said.

"This film is the story of that journey, its effect on them and their ideal of being part of building a new country."
