Bill, a world-traveling bachelor, adores his twin nephews and plans an unforgettable Disney World trip for them, his brother Victor, and their parents. But before the celebration, his sister-in-law Emma drops a bombshell — he’s not invited to the boys’ birthday party because, in her words, he’s not “real family.”

Hurt but undeterred, Bill moves forward with the Disney surprise while Emma is away on a business trip. Victor plays along, telling Emma they’re going camping. The vacation turns out to be a dream — filled with laughter, rides, fireworks, and priceless memories. The boys are overjoyed, Victor finally relaxes, and even Bill’s stoic dad joins in on the fun.
