Luke continues to look for a connection between his son’s disappearance and his father’s old case files while Helen is prepared to do whatever necessary to get information that could reunite her with Anthony. Despite Susan’s warning about working against her investigation, Henry continues his own search for answers.

Susan and Charles focus their investigation on Stephen Price – their main suspect in Anthony’s disappearance. Still driven to pursue his own investigation but confined to a hospital bed, Henry confides in Fred, Catherine’s patient.

Henry asks Fred for help in decoding the clues left by Anthony’s abductor. Luke and Helen still believe their son's disappearance is related to Henry's past. Susan makes an important discovery and issues an Amber Alert.

The police and the Sullivans race to find Anthony.
