The multi-weight Gigi is surprised by her boyfriend David with a couples' trip. But in reality, he has enrolled her in a fat camp. Gigi fights her way through the challenges of the program for the sake of her boyfriend. When Gigi goes on holiday with David, she soon discovers his surprise is a fat camp instead of a couple's suite. While trying to escape, she meets Noah. Gigi stays for David's sake, tackling the program with cabin mates Ava, Tonya, and Mali, learning the camp focuses on more than just weight.

At the annual games, the grand prize — a spa stay in David's hotel — drives her competition, though she bends rules, ending up at Noah's diner while teammate Mali eyes coach Tobi. As items disappear, assistant Benny suspects Gigi, just as an accident disrupts her shifting weight loss plans. Needing a break from persistent David, Gigi leans on new friends, questioning Noah's sudden friendzoning. As the closing party nears and David arrives to pick her up, Gigi's summer camp journey tests relationships, self-discovery, and whether this chapter — and her romance — will end.
