For 12-year-old Ash, change seems an inevitable, and sometimes unpleasant, constant. Her superpowers come and go, rumours are spreading about Team ASH’s missions, and Ah Ma’s worsening dementia affects her memory and behaviour. Thankfully, the Good Ol’ Days daycare centre in their neighbourhood offers seniors a safe environment and fun activities to keep them engaged on weekdays.

But when its future is suddenly threatened by a mysterious, rich couple with plans to turn it into a luxury spa retreat, Team ASH must quickly intervene to save Good Ol’ Days. As they reunite in the final instalment of this heartwarming trilogy for what may be their final — and most high-stakes — mission yet, they learn that change may not be easy, but that care and community can make the journey a little less lonely.
