Sounds like the plastic BB is fucked but I'd be surprised if the frame BB threads are stripped. Even with a steel BB cartridge it's difficult to strip the frame threads unless you've only just started screwing it in.
You could smack the spindle with a mallet from the other side. Worth a shot.

Might as well try and save it first. Put the frame on the ground (as it looks to be) and place wood under the NDS axle. Stick a door mat on top of the bike frame and kneel on it - this will apply pressure to the cup to come out. Now unwind the cup, remember that on BSA threads (most) that both cups wind out the same way as the crank goes round when pedaling.

Removed an ancient bottom bracket from an old frame, cleaned and lubed the threads, stuck a new BB in...and this happened. It got in to this point and now no matter which way I thread it's just spinning in place (by hand). I can't remove it and I can't thread it in any more. Safe to say it's all fucked?
Yes this is plastic
