What actually happens if a person was to be in the space

If a person was in space without the suit, just plain clothes, what actually happens?

In the movies, all that happens is that they can't breathe.

I heard from a source I do not remember, that your body would get severely burnt, and just by my own thinking, would our insides get inflated as well?

You would either freeze to death or burn to death, then your body would be severely compressed. Meanwhile, the millions of tiny fast moving particles would punch holes straight through your body.

You're body would be crushed by its own mass because of the pressure in space.
