Angels of Mercy (1985)

Vanessa (Keli Richards) overhears, by means of an inverted glass placed against the floor, a conversation that leads her to believe that David (Tom Byron), her downstairs neighbor, is afflicted with a terminal medical condition. She relays this information to Raquel (Buffy Davis), the apartment manager, who has dropped by to collect the rent and a half-cup of sugar. One way or another, the story spreads among the building's female population, each of whom wants to provide the bewildered but appreciative David comfort in his final days.
