UH! What now?

[mongidig]

20-40 live 9 handed.

Two eps limp, I limp with JdTd in MP, next player calls, cutoff calls, button raises(No Read, seems decent though), BB and all the rest call to the cutoff(TAG) who now reraises, the button caps and everyone calls.

The flop: Ad7d3c

It is checked to the cutoff who bets, button raises, BB reraises(She is super aggressive, could have a monster or could just have an Ace little kicker. She is an other wise solid player but can't get away from a hand. She reads people well but doesn't always act on her reads). Now here is the scary part. UTG(TAG) call, UTG+1(Tight passive) calls and now it is up to me.

What would you do?
