Nixon works on her to find the baby, while Fletcher works on the mother, who is arrested when she claims she got rid of the child. It appears she left her daughter at St. Hugh's, but the great-grandmother did pick her up. Fletcher and Casper find the child, but Stone only acknowledges Fletcher's part in the finding of the baby, and Casper hands in his resignation when he is offered a security job in Ibiza. Meanwhile, Dasari and Hunter help Louis Dreyfuss deal with a man blackmailing his wife.
