When a camp counselor offers evidence that three children who died in a boating accident at camp thirty years ago were actually murdered, the Squad investigates the claims.

His investigation soon takes him into the world of male prostitution, where he soon finds a young straight man named Rick who is trying to make a few bucks willing to give him as much information as he can. Meanwhile, Ali's friends at the station are determined to find her a man, but a disastrous bar setup and a matchmaking barbecue at Len's confirm that the only thing Ali needs a man for is occasional relief.

Sam finally gets a case of her own -- the three year old beating death of a homeless man -- which leads the squad to a company that tapes homeless people fighting to sell on the Internet.

His objectivity is seriously challenged when he finds himself falling for Lila, the innocent sister of one of the main suspects.

After a taxi driver reports a passenger who seriously gave him the creeps with his misogynistic views on women, Ali decides to look into it, and the trail leads her to Ian Summerhill, a dentist who had dated the first missing woman and had been dating the woman found a couple of days after the cabbie came in.
