A cartoon character in a red jumpsuit and white helmet skydives with a parachute, descending over a green landscape, while a grey and white cat with a smug expression is superimposed in the bottom left corner. The scene abruptly cuts to a live-action street view of a marathon with runners and flags, where the same cat remains in the corner, now with a text overlay reading "Boston Marathon," before the image cuts to a large explosion on the street.
