Did he go through the overflow plate instead of the drain?
This is the first thing to do.

If that doesn't work... Back in high school and college I worked at a plumbing supply house (where plumbers shop for their material).
We carried a product, that MUST be used with caution, but is available to the general public, called Thrift.
This product is a crystallized drain cleaner (not liquid). The stuff is reactive to hot water and will eat through just about any clog. It is the stuff the pros went to when a chemical solution was called for.

If you use this stuff be sure to read all instructions and warnings before opening it. Wear gloves and eye protection, flush your pipes after, but it definitely works.
Also if you are going to try to plunger the tub drain,you must open the "cover plate" "clean out port" or whatever you call it and put some kind of stopper or block in the pipe mouth in there,or the pressure pushed by the plunger will simply blow in and out of that pipe and not be transmitted any further.

OP here. We sent the auger down the (removed) over-flow plate three times. Nada.

A special thank you to N1CKV who mentioned using Thrift drain cleaner. I ordered it from Amazon, and it worked! It created sort of a small explosion after activating the product with hot water, and the drain started flowing immediately.
