The bad news is that the audio is the tiny darker blue waveform along the bottom which is recorded at an extremely low level.
You might be able to make it audible by dragging the "volume Line" up but the quality will be poor.
Re-shooting is the only way to get it back and I guess that is probably not possible.
The ghostly waveforms you can see are called Reference Waveforms and are used by some people as an aid to editing audio, though I don't fully understand them.
You can turn them off in the preferences.

Neil once gave you this reply, quoting the Help
You refer to the 'Reference Waveforms'
Taken from the Help Document:
A reference waveform shows the maximum visual resolution possible for the actual audio waveform. By factoring out loudness changes, reference waveforms let you see the details of the sound more clearly.
1. Choose Final Cut Pro > Preferences, and click Editing. 2. Select the “Show reference waveforms” checkbox.
When the actual waveform changes shape (for example, when it is diminished because a clipʼs volume level is low), its full reference waveform is still visible for easy reference when editing.
or, in other words, found here
The ghosted waveforms in the timeline represent what the audio would look like if it was normalized. It shows more clearly the peaks and gaps. This is non destructive and is for display purposes only
so, there is hope to raise the volume to some hearable level...
but who needs audio anyhow
when you have such a picture?
(dirty ol' man perspective )
• dubbing and some neutral cut-away (to avoid any synch probs)
• is it some racing scenery or somethin'? overlay some loud car-noise and add a sub-title "Sorry - she said: "......."
