Teachers from two very different schools are followed as they try to form a choir at an inner London homeless centre.
Neill Parrish is from The John Roan Secondary School in Greenwich and Paul Cozens is from the independent St Paul's Cathedral School.
One thing they do have in common is a love of music. They've been challenged to put on a carol concert in the capital's famous Spitalfields Market, and they have just two weeks to get their choir ready.
The highs and lows of their rehearsals are recorded, as two very different worlds come together for an event that will see them all finding their voices.
