Edge of Darkness is a 2010 conspiracy crime thriller film directed by Martin Campbell, written by William Monahan and Andrew Bovell, and starring Mel Gibson and Ray Winstone.

This was Gibson's first screen lead since Signs (2002), and follows a detective investigating the murder of his activist daughter, while uncovering political conspiracies and cover-ups in the process.

At South Station, Boston, homicide detective Thomas Craven picks up his daughter Emma, who comes home to visit.

On the car ride and at home, Emma feels increasingly unwell, vomiting and suffering a nosebleed.

While formally identifying Emma's body, Craven takes a lock of her hair as a memento, then returns to duty to help find out who wanted to kill him.

Bennett claims the firm is working on clean nuclear energy, but refuses to go into detail.

Craven repeatedly has visions of Emma's past, including short conversations, typically as the happy young child he remembers and loves.

Jedburgh suggests that portraying it as an assassination attempt on the Senator could be an angle to keep Bennett's death out of the headlines.

A young reporter for the local TV station, who had spoken to Craven a few nights earlier, opens a letter from him which contains DVDs recorded by Emma revealing the conspiracy.

Additionally, Gibson and his crew set up shop for filming in western Massachusetts, with 180 staff staying in Northampton hotels.
