French & Saunders (1987)

S1E5 Happy New Year, Aunt Carrie

Aunt Carrie, confined to a wheelchair, is ringing in New Year’s Eve with her young niece and nephew when the sound of gunfire shatters the celebration. Peering out her window, she sees a murder unfold in a neighboring apartment across the courtyard. As she locks eyes with the assailant, she realizes he’s now aware of her presence and may target her next. However, the killer underestimates Carrie; despite her physical limitations, her intelligence and cunning far surpass his.
