Kind Lady on IMDB
Wealthy and charitable Mary Herries is tricked by aspiring artist Henry Abbott into letting him and ill wife Ada stay in her stately home.
When he invites friends Mr. and Mrs. Edwards to pay a visit, they overstay their welcome as well. Days turn into weeks, making Mary and housemaid Rose increasingly anxious for everyone to leave.
It turns out to be a plot masterminded by the silky and sinister Abbott to steal everything Mary owns. He masquerades as a relative and they as her butler and maid, holding Mary and Rose captive in their rooms. Outsiders are told that Mary has gone on holiday to America and won't return for a long time.
The plot thickens as Rose is killed. The suspicions of Mary's business adviser, Foster, are confirmed when no record of Mary applying for a passport can be found. The police arrive just in time to save her and place Abbott under arrest.
