Two clones on an outpost in the middle of nowhere are field-testing some equipment, when things go wrong.
I like flick-fire missiles when they are well designed, but sometimes I see one in sets like Clone Troopers vs. Droidekas and am annoyed by how unrealistic or badly designed the missile placement and firing range is. Sometimes flick-fires seem to be placed just because LEGO wants a flick-fire in every set.
