I do not understand where this is coming from? But the guy is just giving directions , like ...''Good ,take notice'' , ( then another part because others are talking I can not make it out )then ...''OK, three ,four,'',,,,, and action! ''to work '', ''run run ,work!(in the sense of move, move!) when they stop. The director says ''Then do something with her'' (a joke). ''wait, what went wrong?''
This seems to be for some film like series on TV ?? The names written on their backs is 'stretcher-bearer' A lot of noise in that place talking ,banging, I would say, some film for TV? ( for foreign TV?)
