Synastry: Her Moon conjunct Venus trine his Sun conjunct Mars

Okay, here is a question. The girls has Moon conjunct Venus in his natal and guy has Sun conjunct Mars. Those planets trine in synastry! It's very good thing, i believe. But! There is a problem. Her Pluto is opposite his Sun and Mars, and his Pluto squre her Moon and Venus!
What are your thoughts? How this relation could look? Please help!

it is always helpful to post a chart.

I will second the above, one or two good aspects in syntasry and one or two bad ones can't really be taken into account without seeing the overall chart.

I too would like to see the chart but my comment on only the info given is that those pluto aspects are very heavy (thou extremely hot and sexy) and it will take more than a moon conjunct venus to mitigate them

Ie it spells trouble
