They're never up to any good. Like, you know, helping a guy propose to his girlfriend.
I haven't the faintest idea what any of this is about, since the video is in Russian, but given the change in music from Rammstein to some vaguely pop, it seems like that's the cue for the switch.
It's nice to see a Russian video involving motorcycles that doesn't end with biker parts all over the road...
That is all.
