Included is a glimpse at a completely different ending in which Sandra finally gets to introduce Sonny to her friend, which turns out to be Kira, who's dancing with Danny.
If you want to see total known since I'm people just dancing and not saying anything I'm just total idiocy it doesn't make even sent to see the movie because the movie makes no sense at all but then definitely not a documentary wouldn't make sense whatsoever to see and because of this you shouldn't see it in China.
