Complex sentence analysis

Is this the correct analysis of the sentence?

She(S) has tried to show(V) that what you would have to assume in order to acquit my client is simply beyond our normal understanding of what is reasonable(d.O)

but the there is also a that clause which I analysed on it`s own:

that what you would have to assume in order to acquit my client (S) is (v) simply beyond our normal understanding of what is reasonable(sP) ????

Am I completely lost, or what? It is so confusing with these complex sentences..
