A group of children desperate for a mother's love will kidnap Rosalee Calvert (Bree Turner) in the upcoming episode of the NBC series "Grimm."

In "Lost Boys," TV Guide reports that Rosalee will be missing and the team will suspect it has something to do with a band of orphans desperate enough to take in anyone whom they can call mother. When Monroe (Silas Weir Mitchell), Nick Burkhardt (David Giuntoli), and Hank Griffin (Russell Hornsby) learns of a similar case that ended badly, they are horrified. The three must not waste any second to locate their colleague, or they will be facing another tragedy. Will they find her on time?

Last episode, the squad was involved in investigating the murder of the CEO of a large investment firm. The culprit was a Wesen who was wanted for embezzling money. Beau Childs (Gary Kraus) had the misfortune of hiring a monster employee named Paul Wemlinger (Jonathan Slavin). When he discovered that almost half a million dollars was missing, he asked the Wesen to investigate. Wemlinger brutally murdered Childs, then tried to pass off his death to robbers.

Monroe, however, thought something smelled fishy with Wemlinger. Once he got the chance to bring him to the station, he called Nick to confirm his suspicion that the employee was a Wesen. Nick saw that he was a Quijada Vil, something the former has only read about before. Before they could apprehend him, however, U.S. Marshals arrived to get Wemlinger. Apparently, he was a wanted man due to his stint in Sacramento.

The soldiers left with Wemlinger, never expecting that he would easily kill them. When Nick and Monroe got to the scene, the Wesen was gone. They traced him to Child's assistant's house. The woman tried to convince them she was also a victim, until she woged into a Fuchsbau. Wemlinger tried to kill Wu (Reggie Lee), so the sergeant had no option but to shoot him. The assistant jumped out of the window and was also killed. Nick and the rest were left with two corpses and more questions than before.

"Grimm" season 5 airs Fridays at 9 p.m. EST on NBC.
