Ousmane and Mrs Sommers are both humble people living ordinary lives -- he in France and she in the Channel Islands. He has a son, and she has a daughter. They both are students in London. On July 7, 2005, without any news of their dear children, they decide to start a journey together in search of the two teenagers. And, although they come from different religious backgrounds, Ousmane is Muslim and Mrs Sommers' Christian, they will share the same hope in finding their children alive. Putting aside their cultural differences, they will give each other the strength to continue the search and maintain the faith.
