A happy young bat accidentally flies off during the day and, as a result, meets wingless mice who get to know his topsy-turvy world.
A happy young bat accidentally wakes up during the day, flies off and hurts his wing in a near-miss with a swallow. Luckily he is found by a family of (wingless) mice who look after him. In turn, they get to know the bat’s topsy-turvy world. There is no dialogue in this stop-motion puppet animation, but there is funny brass band music.
