When eleven-year old Tim visits his grandfather with his mother and new stepfather, he refuses to accept that the strong, steady man who helped raise him has Alzheimer's disease. Tim persuades his grandfather that going on a secret fishing trip with him will prove to the rest of the rest of the family that he is still the man he always was. When the mistakes begin to snowball, Tim is forced to admit that Granddad isn't as capable as he once was...but his realization may have come too late.
