Greg's family has cut back on vacations and day trips to save money, limiting Greg's summer fun. During summer vacation, Greg enjoys playing video games inside while his mother starts a book club. Greg and his friend Rowley run up a $83 bill for smoothies at the country club they thought were free. Greg gets a job to pay it back, but his plans to mow lawns go poorly. His birthday money will have to pay the bill instead of buying the dog he wanted.
