Booth and Brennan are called to the scene when an El Salvadoran gang member is found with a corpse of a woman in the trunk of his car. As he is questioned at the scene, a drive-by shooting gives him an opening to flee police custody. Booth and Brennan find where the woman was originally buried -- a soon-to-be-excavated community garden -- but find another empty grave nearby. Their investigation leads them to a wealthy senator's estate where the truth is hard to come by.
