Dean is a supernatural hunter with his little brother, Sam or as he calls him 'sammy'. Their uncle Bobby, more like adopted dad at this point, does cases with them and so does their angel friend, cas.

While on a case they met a girl that is good at hunting as well, Jax Black. Jax is a good hunter but also very flirty, everyone is used to it by now. Dean is in love with Jax, but don't ever say it because he's not used to dating or 'love'.

Dean and Sam need help on a case so they call Jax.
