Allegra (Maureen Lipman) is full of joy. So much of it that she cannot stop herself from bursting into song.
At home, in the street, even in shops and restaurants. Sometimes the music is only a fantasy in her head. But at other times, it results in a loud and disruptive performance that causes chaos in the village where she lives.
Allegra’s brother, Ronen, and her carer, Anna, must somehow control her eccentricities and avoid angry visits by the local policeman. But is this possible without destroying the great happiness that fills Allegra’s heart?
Allegra is a moving comedy with spectacular song and dance sequences, but is also a touching and emotional examination of how, sometimes, the most beautiful of minds can start to disappear.
