Okay, we seem to have established that you are using an EOS 5D Mark III camera with the 128GB CF card.
That camera body has two card slots, a CF card slot and an SD card slot. Do you have cards in both slots? If so, then check both cards for your missing files.
How are you reading the CF card? Are you using a card reader, or connecting to your Mac via USB cable?

Using a Transcend memory card reader via USB to my Mac. The only card I've ever used in this camera is the CF card pictured above.
Okay. It does not sound like this is the first time you have tried to transfer files, anymore. Do not place the card back into the camera! Usually the best way to determine if there are files on a memory card would be to use the camera to browse the memory card. But, this can also cause problems for a card that has been removed and then re-inserted. The camera will try to initialize itself to use the inserted card, which can “erase” existing files.
During the event, did you try to erase any files? The consensus opinion says deleting files in the camera should be avoided like the plague. Deleting the most recent file, like the last photo you shot, seems pretty harmless. But, going through the card and deleting select files here and there is where trouble can begin.
If you are certain that files should be on the card, then I suggest that you visit the Sandisk web site for a recovery program.

A couple things, is there another card in the camera? Go check again. It will be a smaller SD card. You should have noticed the red light blinking as it files your shots. If, yes, it stored them somewhere. Get ahold of Transcend and d/l their recovery software. You may need it. Lastly a 128GB CF card is way, way too big. You should try to use several smaller memory cards. That way if one does go south, you don't lose all your work or shots. I use 16GB CF cards.
Do not use that CF card. Do not format it or delete anything from it. This will make recovery difficult to impossible. Try a different reader and/or USB cable. Even a different MacBook. Good luck!
