A group of bikies converged on Sydney airport. Within minutes, one was dead and others injured. It was an incident that set off one of the world's most intense and effective gang operations, and led to a plethora of law changes and high profile convictions.

Deborah Wallace is a titan of NSW Police. Retiring in 2019 after 36 years in the force, she became known across Australia as 'The Gangbuster', after successful operations in the intense region of Cabramatta, and then the aforementioned Strike Force Raptor.

The beginning of her career though was much more abstract. She was involved in one of Australia's most horrific cases. The rape and murder of Anita Cobby in 1986.

Understand the impact of that case on Deb, and Australia as a whole as Brent Sanders steps through the career of one of Australia's most decorated police officers.
