Duck Dynasty is getting serious.
When the A&E show ends its fifth season Wednesday night, it will focus on Mia Robertson, the 10-year-old daughter of Jase and Missy Robertson, who was born with a cleft palate and received corrective surgery, which is documented in the show.
"You're gonna go from gut-wrenching laughter to crying, because it's very sweet," Missy tells PEOPLE.
