"Elizabeth notices strange weekly alerts that her backyard gate unlocks every Wednesday. Suspecting her husband Richard’s affair, she changes the gate passcode, hides a note under the mat and installs a hidden camera. Footage shows a woman named Catherine trying the locked gate and ringing the bell. Elizabeth signs divorce papers and leaves them under the mat.
Richard confesses Catherine is his old classmate, whose daughter Lily suffers from leukemia. He secretly lends her money weekly to avoid Elizabeth’s misunderstanding. Elizabeth forgives him, offers all their savings and accompanies the pair through Lily’s surgery.
Lily recovers fully. Catherine lands a stable accounting job, and the two families grow close. Elizabeth leaves a new note under the back gate, promising constant help. When a desperate stranger with a sick child knocks at the front door on a rainy day, Elizabeth warmly welcomes them, for her home’s doors are always open to those in need."
