White Lines: Jane, now officially an FBI consultant, is called to Corpus Christi to help find the killer that shot up a DEA office and murdered six federal agents. A surviving agent believes that the gunmen where part of the Gulf Coast Ring; a vicious drug ring that the DEA busted last month. The DEA suspects that the leader of the Gulf Coast Ring is a local businessman with a legitimate front, and they hope that Jane and the team can uncover his identity.
