Fat Rose and Squeaky (2006)

The Irish-willed eighty-year-old Bonnie Ash Fitzpatrick and her only friend in life, seventy-year-old Celine Snow disagree on just about everything. When Bonnie's long-lost niece, Christine, attempts to trick her out of her house, the two friends come up with a plan. Using Bonnie's association with the wacko neighbors (Fat Rose & Squeaky) as examples of her inability to safely care for herself, Christine's plan appears to be working. The friendship between Bonnie and Celine proves to be a greater challenge to Christine than her aunt's age.
