Jack is a former jeweller who made his living buying and selling diamonds via late-night TV ads. He lives in a rather luxurious, privately-owned retirement home along with his fellow residents: the visually challenged techno-wizard Rose, the artistically gifted but forgetful Flora, and the narcoleptic beauty Blanche.

Unbeknownst to the four of them, however, the man to whom they've entrusted their life savings -- a smooth-talking financial advisor named Barney Effward -- has been arrested for bilking his clients out of their savings through a Ponzi scheme.

Faced with financial ruin, the four suddenly find themselves confronting the author of their miserable fate when Effward is unexpectedly delivered among them -- along with several million dollars in diamonds. Pandemonium ensues as the four retirees try to find a way to exact their revenge, recoup their losses, and keep the authorities from discovering their plans.
