The Client (1994)
A street-wise kid, Mark Sway, sees the suicide of Jerome Clifford, a prominent Louisiana lawyer, whose current client is Barry 'The Blade' Muldano, a Mafia hit-man. Before Jerome shoots himself, he tells Mark where the body of Senator Boyd Boyette is buried. Mark escapes, and Clifford shoots himself. Mark is found at the scene, and both the FBI and the Mafia quickly realize that Mark probably knows more than he says. Mark decides he needs a lawyer, and goes looking for one. He finds Reggie Love, who also becomes convinced that Mark knows more than he says, but Mark isn't talking.
