"A lifetime's worth" singular or plural?

My little blurb thingey: Does a lifetime's worth of royalty statements flash before their eyes as hit?

"Does" just doesn't seem right, yet lifetime's worth would be singular. But if it modifies 'royalty statements', which is plural...

I navigate grammar via the moon's phases and certain arcane words inscribed upon the walls of long-hidden caves. I am at a loss.

I think it's "Do."
