Ali is a police of Scotland Yard, the headquarters of the London Metropolitan Police. He was born in Lahore, Pakistan, then married a British woman and had two children. After the London bombings in July 2005, Ali was ordered to investigate a related suspect, but the work did not go smoothly. Meanwhile, as a Muslim, he had worked at Scotland Yard for many years, but due to the bombing, he was also looked at strangely by his colleagues. Although the truth was finally revealed, the discrimination he experienced during this period and people's fear of the bombing made it hard for him to let go.
