Robert De Niro is set join Mel Gibson in Edge of Darkness, the Martin Campbell-directed thrilled.

According to Variety, Gibson will portray as Thomas Craven, a straitlaced homicide detective for the Boston Police Deptartment and single father. His 24-year old daughter is murdered on the steps of his home.

Craven assumes he was the target, but his investigation leads in another direction, as he uncovers his daughter's secret life, a corporate cover-up and government collusion.

De Niro will play an operative sent to clean up the evidence.
