"Edge Of Darkness" (2010) Mel Gibson is Boston PD Detective Tom Craven. When his 20-something daughter Emma comes to visit, she is shot to death on his front porch. Thinking that he is the intended victim, Tom soon learns of Emma`s secret life as an activist, about to expose the large corporation that employs her. A suspenseful drama that seems very familiar to me....I see bits and pieces of "China Syndrome", "The Firm", and "Shooter" all rolled up into one plot.
