Mantis in Lace is a 1968 sexploitation film directed by William Rotsler and starring Susan Stewart, Vic Lance, Steven Vincent, Pat Barrington, and Stuart Lancaster.

She continues to pick up men at the bar where she is employed, but after her sanity is lost she routinely is interrupted mid-coitus by psychedelic bad trips in which she visualizes a balding, half-naked old man clutching wads of cash in one hand and a bunch of bananas in the other.

These psychotic episodes cause her to murder her partners by stabbing them with a screwdriver and dismembering them with a rusty meat cleaver (or in one case, a garden hoe) while imagining that she is cutting up cantaloupes and watermelons.

[1][2] As pieces of the victims' bodies are discovered in cardboard boxes, she is pursued by a pair of Los Angeles Police Department detectives played by Steven Vincent and M.K.

The music score, relying chiefly on an electric guitarist who seems to be making up stuff as he goes along — none of it worthy of the term "improvisation", mind you — lurches from quirky kitsch to agonizing irritant very quickly.
