Ballard (Callie Thorne) and Gharty (Peter Gerety) run up against a wall of confusion as they investigate the murders of two women who were felled by a stun gun and strangled after accepting drinks from a kinky married couple. Things get more and more curious when one of the suspects makes a full confession -- which turns out to be a lie from start to finish. Meanwhile, Lewis (Clark Johnson) turns over important information relating to the Mahoney drug shootings. ~ Hal Erickson, Rovi
