Florinda Bolkan plays the daughter of a prominant English politician who keeps having recurring &quotnightmares&quot in which she makes love to a bisexual nympho who lives downstairs and conducts all-night LSD orgies. When the nocturnal wet dreams become murderous, the neighbor turns up dead, and Florinda is the main suspect. Did she actually commit the murder she dreamt about? Is she being framed by her philandering husband? Did Florinda actually make nightly visits downstairs aside from borrowing the occasional cup of sugar? How DID Florinda&#39s letter opener end up stuck in the dead neighbor&#39s chest anyway? The complex plot unfolds amidst red herrings, outlandish dream sequences, lesbian hanky panky, and ominous close-ups of Florinda Bolkan&#39s guilt-ridden facial expressions every time someone mentions the murder. All this takes place in swinging late-1960&#39s London.
