(4 Score & 7 Years Ago)
a common trope at the beginning of an episode or movie that mostly shows up in western animation, but occasionally live action is when a group of kids (who aren't usually relevant to the plot) are playing football, frisbee etc until the item get's launched somewhere far off. one of the kids goes to get it and discovers something e.g. a supernatural creature or a dead body. or the child is killed, kidnapped or something else harmful happens to them, depending on the setting e.g. stunned with a spell.
it's not always with children but it's the most common.
