Boyd got out, Spencer got shot but is not dead, that was where the series ended, the will he or won't he cliffhanger, Stella was the one trying to erase any data etc. that would lead to the bad guys (which were of course the government) she was doing it at the request of her guardian Commander Drake (he's Boyds boss). Spencers friend (who also used to be his boss) was the murderer and he also went to finish Spencer off at the end but ended up dead himself. Stella begged Boyd to let her stay with the unit (can't remember if he did or not, probably another thing to find out in the next episode) Felix was okay after a package blew up in her face (this was meant for Spencer). It's hard to try and explain it all when you didn't see any of the episodes but you've got the jist now, if you want to know anything else let me know.
