Lovesick and desperate, sculptor Brindsley Miller has embellished his apartment with furniture and objects d’arte “borrowed” from the absent antique collector next door, hoping to impress his fiancée’s pompous father and a wealthy art dealer. The fussy neighbor, Harold Gorringe, returns just as a blown fuse plunges the apartment into darkness and Brindsley is revealed. Unexpected guests, aging spinsters, errant phone cords, and other snares impede his frantic attempts to return the purloined items before light is restored.
