Summer has finally come, but Manolito is stuck at home while all of his friends head off on vacation. To fill the time, Manolito and his little brother go to Hangman's park or the swimming pool. The summer seems to be boring until Manolito makes a new friend, Mustard. The two of them begin to play games together and when Big Ears comes back it is a little awkward trying to find time for all of Manolito's friends. He is growing a little older and now is learning how to balance things without giving up one important thing for another.
