All hell breaks loose when Pop's wealthy, estranged brother, owner of Cavanaugh Bros. Construction and Chuck's boss, James ""The Weasel,"" pays a visit to the Cavanaugh house, against Pop's wishes. James wants Pop to know that an old basement office they once shared is going to be demolished. Inside the office is a locked safe, each of them has only half of the combination, and Pop stubbornly refuses to hand over his half. The two brothers are forced to work out their 30-year-old differences when they both arrive at their former office. But their bickering causes the staircase out of the building to collapse, leaving them trapped inside just hours before the demolition. While looking for a way out, Pop finally agrees to share and share alike, and his seeing the prized family memories that James saved in the safe leads the pair to have a reconciliation right before Chuck and Kit rescue them.
