When the nocturnal wet dreams bee murderous, the neighbor turns up dead, and Florinda is the main suspect. Did she actually mit the murder she dreamt about? Is she being framed by her philandering husband? Did Florinda actually make nightly visits downstairs aside from borrowing the oasional cup of sugar? How DID Florinda's letter opener end up stuck in the dead neighbor's chest anyway? The plex plot unfolds amidst red herrings, outlandish dream sequences, lesbian hanky panky, and ominous close-ups of Florinda Bolkan's guilt-ridden facial expressions every time someone mentions the murder. All this takes place in swinging late-1960's London.
