At the concert hall, a terrorist points his gun towards the choir group and starts shooting at the members. As we hear screams of terror from the audience, others join in the choir and keep the chorus alive. The choir stands together and sings on. The terrorist fires more shots, but less screams are heard and more people join in to keep the choir alive. The terrorist runs out of ammunition. The strong choir sings together in harmony. The terrorist leaves his gun behind and joins the choir.
