The team receives a call about murdered Navy Captain David Wade who was picking up his daughter Lydia and her friend Rosie from work. Two men had ambushed the girls and abducted Rosie, killing Wade as he tried to rescue them. Lydia receives a text message from Rosie pleading for help and the team tracks the signal of the pre-paid phone to a trailer where they find the phone near a dead man identified as Shawn Oakby. They find pictures on the phone of Rosie in provocative clothing and Gibbs determines they were planning to sell her. Ducky uncovers anti-sweat chemicals on Oakby's hands used by athletes and they suspect the perpetrators are tied to the local bowling alley where a vigil was being held for Rosie. While Abby and Ziva look after Lydia at Gibbs' house, Fred the bowling alley manager breaks in and attacks the women, but Abby manages to take him down with a frying pan. They arrest Fred and he confesses he was the set-up man for the trafficking operation. He had feared that Lydia would remember details of the men from the kidnapping and tried to kill her before she could identify them. He also gives up that he was working with Oakby as well as another man named Merle. Gibb calls upon his old contact Miranda Pennebaker for help and she uses her sources to ascertain details of the unknown buyer the men had been working for. Pennebaker's source uncovers the buyer's name and the location of the planned sale of Rosie. The team arrests Merle as the buyer's helicopter lands with Rosie inside. DiNozzo expresses jealously of a man Ziva has a close relationship with only to discover that he is an older mentor figure of hers.
