What happens at the zoo when all the people have gone home? Max and Mia are very excited about their school trip to the zoo. But when they arrive, not much is happening: the zebra is asleep, the lions are hiding, and they can't even see a monkey. Max and Mia make the best of it after all, if you look very carefully, there is something to see everywhere. But when they are accidently locked in the zoo at night, they realize that midnight is when the zoo comes alive! Flamingos are doing the flamenco, the lions dance till dawn, and the pandas have a party. Morning comes all too soon and it s time to go home, but Max and Mia will never forget their night in the zoo!"
