Obvious, but Unbelievable (1982)

During a busy lunchtime in a cafeteria, a normal scene unexpectedly becomes chaotic. As people eat and talk, something happens that disrupts the peace, forcing diners to react. The film examines how people interact in unpredictable situations and the bravery it takes to help when something goes wrong, all within the familiar setting of a school canteen. It looks at how people respond – from watching to stepping up – and the feelings that arise when everyday life is suddenly interrupted.
