Going to Babylon

When a man is found dead on the side of the road, the death appears to have been caused by a heart attack, but the two cops don't think all is as it seems. Chris and Rita suspect that a couple is luring ""amateurs"" to their dungeon for ""sometimes lethal sex."" So Lance and Lorenzo go undercover as a couple of swingers looking to be chosen by the couple, to go to the dungeon. Meanwhile, an old enemy reminds Rita of her father and her youth.
