When Luke’s face appears on a TV newscast about a grief-stricken couple’s search for their missing son, Sarah and Luke’s friends are shocked. Maria’s mother tips the police off about having seen Luke at Sarah’s house, and they descend upon the house to recover Luke and place Sarah under arrest. After a little bit of intervention from UNIT, Sarah is released with no charges filed, but everyone is suspicious of Luke’s “real family” – especially Luke, who finds himself now virtually a prisoner in their home. But when Clyde, believing he has solid proof that Luke is not in the hands of his real parents, calls on Sarah’s computer, Mr. Smith, he discovers that there’s more wrong than anyone realized.
