(A)Torsion (S) (2002)

A singing group, trying to escape war-torn Sarajevo, has to wait for a tunnel to clear. While they wait, a cow has difficulty giving birth because of the "torsion" affecting its calf (i.e., it's in a twisted position inside). Fortunately, one of the choir members has some veterinary training, and with help from the chorus to drown out the sounds of war, the cow gives birth.
