In the fic Burt and Carol are together, though I don't really remember if they're just dating or engaged. Burt, Carol, Finn and Kurt all have dinner with Carols family(brothers?) and they are homophobes. At some point in the story they kidnap and hurt Kurt and Finn and Puck eventually find and rescue him.
I don't remember how it ends exactly.
Thanks in advance for any help.
