"Hail Mary" is broken down into three pitches. The first pitch starts with a jumbled slide into a nearly 90-degree left turn, followed by a sequence of holes and waves.

A short pool brings you to the second pitch: A rocky protuberance separates the flow (at low-to-moderate levels, anyway). To the right, water flows over a shallow shelf and dumps into a wrapping hole (the current from the left line). To the left, a sweet slide accelerates you into the flow dropping in from the right, then (with little pause) accelerates you toward a pretty good sized hole, with diagonal 'feeder waves' funneling you into the maw. Punch the hole hard, angled left to catch the left eddy, or you will be fed (by the outflow) right into an undercut wall.

A longer let-up precedes the final pitch. The jagged rock of the riverbed 'humps' down the middle of this pitch. To the left, water spills into a nasty, narrow crease. (You DON'T want to be anywhere near this!) With adequate water, the most opted for route is more-or-less down the center, but more often when I've been there (with low-to-moderate flows), the preferred route has been well to the right. A short initial ledge drops you into a short pool. Sliding out of there, you grunge down toward a wall of rock (right shore), to be diverted sharply to your left. You do your best to avoid banging paddle or right elbow on the wall (or worse, being flipped) as you head toward the hole formed where currents converge (from the left-side slot) as they (hopefully) spit you out downstream.

This is some serious gradient that you will want to take a good look at. As soon as you see the first 'cabin' (house) on the right, get out to scout the whole section. At low-to-moderate flows, you can easily break it down into three or more distinct pitches, each of which is not that difficult. However, taking the whole sequence together (as will be the case at higher flows), it is a huge chunk of gradient to navigate.
