without a clue

Totally in darkness

Without a clue means completely ignorant or clueless about something.

The phrase suggests someone lacks even the most basic understanding: She walked into the meeting without a clue what they'd been discussing.

It can also describe general incompetence: He's trying to fix the plumbing without a clue.
