Some explanation is needed. Zabel is a dead satanist rocker that was revived by Hombrela (and given some cool powers). The two guys he and Chris are talking about are members of his band, so he goes after them to Culiacán, a big city well known for its problems with drug cartels.
Anyway, Víctor and Jill are closer and closer to discover the truth behind everything that's happening. Of course Hombrela won't let those two get away, so they send some mutant frogs.. I mean, toads after them!
