In Louisiana's Atchafalaya River Basin swamp, Troy Landry and his son Jacob finally catch the "big one" -- an alligator nearly 13 feet long.

"Go!!! We got 'im!" Troy screams. "This is the one ... Two years we been trying to catch this alligator," says Troy on the premiere of 'Swamp People' (Sun., 10PM ET on HIST).

The gator is so big, a crane has to move it into the storehouse. Troy enjoys showing off the 12-foot, 11-inch record-breaker, but later settles down for a quiet, home-cooked dinner of seafood (what else?) with his family -- his main priority. "Family comes first. There's nothing more important than family. Nothing."
