She rushes to the police station, where she's told to wait while they file a report. But when she sees all the posters for other missing children, she realizes that waiting was probably all that the other parents did. Karla is not one to play the waiting game, and goes on a relentless pursuit to find the kidnapper and get Frankie back herself.
