Is "be out in the open" an expression? If I use only "be out", can it deliver the similar meaning?

Yes, to "be out in the open" is an expression that means to have everything exposed, revealed, or known about. If you only say "be out", it could mean the same thing, however, it would not express the same meaning very clearly. Ex: He admitted to his lie. Now everything is out in the open. Ex: Now that everything is out in the open, are you mad at me?
