It's the 40-year anniversary of Duck Commander and this celebration is a redneck Robertson style shindig. To top off the event, Willie decides to construct the world's largest duck call to be revealed at the party.

When Willie finds out that his daughter Sadie has a new boyfriend, he wants to get to know him, while instilling some fatherly fear--Robertson style. To keep Sadie preoccupied, Grandpa Phil and Uncle Si take her on their own outing.

To prove once and for all who rules the river AND the boardroom, Willie and Jase revive their childhood rivalry and go head-to-head in a fishing competition with the added challenge of having to sell their catch.
