In season 8 opener, to catch a group of kidnappers targeting newborns, Sydney and Gage play the role of the parents of the most recent baby-napping. Meanwhile, Alex encounters a man trying to force tenants out of rent-controlled apartments and convinces a judge to halt the owner's attempt to have the place condemned so he can demolish it to make room for a strip mall. When a boy accidentally witnesses the owner's accomplice sabotaging the building's furnace (so the owner could demolish the building without being held liable) and is trapped, Walker must rescue him before the building collapses.
