Finding that elusive mid-point milestone

Last night my husband and I saw Leap Year. He's now sucked into my little game-- identifying the first plot point, the mid point milestone and the second plot point in the movies. Leap Year, besides being a wonderful romance flick (btw the chemistry between Amy Adams and the Irish dude is incredible!), the three points were a bit more challenging to identify. I won't go into it here, don't want to give away the film if you've not seen it yet! But if you do, try to figure them out. It's kinda tricky!

In my wip, I can easily identify the first plot points for both Marcie (main plot) and Cindy (sub plot). I think I even have the second plot points figured out. But I'm still confused on where the mid point milestones are. I have no clue where Cindy's is. In fact, I'm not sure there is one. I think I know what Marcie's is, but it needs further examining. I didn't get to it during this writing session.

I have a feeling it's there and I'm simply overlooking it. Brooks says that it's obvious, flexible, and easily overlooked by inexperienced writers, or those not accustomed to writing according to story structure. (ha ha, that's me)

He also says, "Before the Mid-Point both the hero and the reader experience the story with limited awareness of the real truth behind what’s going on. Because it reveals significant new information, everything after the Mid-Point carries new weight and dramatic tension."

Okay, this is good. I'm going back in for another look. But first, back to bed for my three hour morning nap lol! Meanwhile, something to ponder: What's the mid-point milestone in a story you're reading or writing? Did you catch it? Not sure? Me neither!
