When the mummified remains of an infant are found inside a tree, Weeks and Bender investigate the former residents of the house and learn that the baby was never registered, and the suspects include the mother, who is completely out of touch with reality, and her husband, an ex-convict who is not the baby's father. Ed's former fiancée Marissa calls him in for help when her parents disappear, but it's only a matter of time before Stahl and Oosterhuis discover that Marissa's parents are involved in an elaborate con to bilk people out of their hard-earned money.
Oosterhuis and Stahl investigate the death of Filippino nanny Rhodoura Santos, whose employers hadn't even realised she was missing. The Vucetas swear that Rhodoura was about to be fired because she wasn't a very good nanny, but in talking to other nannies in the park, Stahl and Oosterhuis get a whole different view of things. Weeks and Bender investigate the shooting of Alan Rotteirs, the director of a local youth center, who had announced his plans to clean up the community, in particular to get rid of local tough Bobby Fuentes.
