I want to drive up there and check things out, see what's going on at the scene.

It is going on at the same time as the main action of the program.

An awful lot is going on at the same time.

"You should question what's going on at home that is leading the child to want so much from people she doesn't know."

I think he should be a little more interested in what's going on at home.

I ought to see what's going on at the office.

"You really want to know what's going on at that party tonight?"

"What we deal with is what's going on at the present."

But something else is going on at the same time.

Talking about what's going on at the hospital is not exactly good for business.
