Shortly before nine a.m. on the morning of 7 July, 2005, and again exactly one hour later, a total of four bombs explode in London. At the height of the rush hour, four assassins travelling on public transport activate the ex plosives they are carrying in their rucksacks, killing, within minutes, 56 people and injuring more than 700 others on three underground trains and one double-decker bus. On a video tape that was later discovered, one of the Islamic terrorists announces that his group is at war with British society. Ousmane and Mrs Sommers are both humble people living ordinary lives: he in France, she in the Channel Islands. He has a son, she has a daughter. They both are students in London. On July 7th 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.
