After opening Daddy Day Care, Charlie and Phil decide to expand their business and buys a dilapidated camp they attended as kids, turning it into Daddy Day Camp. The two men soon face foreclosure, low enrollment, and plenty of repairs. The few kids that remain at the camp eventually band together when Charlie's father, Col. Buck Hinton, starts to control the whole camp and eventually the kids start to form a team instead of fighting each other. They then battle the rival day camp in an Olympiad. In the end, the kids prevail and more kids come to the camp saving Camp Driftwood from foreclosure.
