With more than a month away from its fall debut, CBS has released the official synopsis for the Season 3 premiere of "NCIS: New Orleans." Meanwhile, "Hot in Cleveland" actress Wendie Malick has been cast to play the role of Sebastian's mother.

A new member of the team will be introduced on the premiere of NCIS New Orleans Season 3. According to the press release shared by SpoilerTV, FBI Special Agent Tammy Gregorio is sent to investigate Pride and his team following the aftermath of Russo's case. Gregorio will be played by new series regular Vanessa Ferlito (Graceland).

Elsewhere, the season opener will also find the NCIS team partnering with several federal agencies as they track the location of a sniper at large - who they discovered at a crowded festival. The network also confirmed that the exit of Agent Brody (played by Zoe McLellan) will be addressed during the Season 3 premiere.

In other developments, "Hot In Cleveland" actress Wendie Malick will guest star on "NCIS New Orleans" Season 3, Entertainment Weekly reported.
