One of cable's most popular shows, Duck Dynasty, will be premiering its fourth season on Wednesday, Aug. 14.

Fans will revisit the Robertson family during a time of celebration: The first episode will feature Phil Robertson and Miss Kay renewing their vows after being married for 49 years. The central conflict of the episode involves who Phil will pick to be the best man at his wedding.

A&E released a preview of the episode recently, which features Phil's sons, Willie and Jase, arguing over who should be the best man. Watch the preview here.

Viewers will also be introduced to a previously unseen member of the Robertson family: Phil's third son, Alan. Alan is Phil and Miss Kay's oldest son and does not have a beard like the rest of the Robertson men. He will officiate the ceremony in the premiere episode and will make regular appearances on the show this season, according to multiple reports.

A&E aired the first five minutes of the premiere episode on Sunday, Aug. 11. The clip featured Willie playing the board game Battleship with his brother, Jep Robertson. Willie mentioned that he doesn't like to lose, which clearly previews the conflict that will occur later in the episode, involving who gets chosen to be the best man.

Meanwhile, Willie and Jep's wives, Jessica and Korie, talked about Pat and Miss Kay's upcoming anniversary. After noting that Phil and Miss Kay never had an official wedding ceremony, they decided to start planning one for them.

The premiere episode of Duck Dynasty, titled Till Duck Do Us Part, will air Wednesday at 8 p.m. on A&E. The show will feature a new episode every week on Wednesdays at 10 p.m.
