If I were a betting man, and I am, I'd bet the film is toast because it is slide film.
Once at Big Sur, I underexposed most of a roll of K25 because I thought I had K64 in the camera. That's a stop and a third. Normally processed, it came out gorgeous. Deeply saturated, dark shadows, but for the subject matter, it was beautiful.
There is definitely something on the film, and push-processing should be able to salvage enough to make it worth doing, if the images are important. Reshooting would be best, if it is a viable option; if not, and the OP cares about the images enough, then it is worth doing. What Stephen Frizza has said is very interesting; he's not just some guy talking- he knows his stuff.
