Richard Gere stars as hotshot defense attorney Martin Vail, who welcomes media attention as he works to get high-profile clients off the hook on technicalities. A young Edward Norton, in his film debut, co-stars as Aaron Stampler, an altar boy accused of killing a powerful Catholic archbishop, who insists that hes innocent and that his violent behavior is the work of a second personality called Roy.
