Playing with Fire is a play about sexual frenzy, illicit coveting, exhibitionism, voyeurism, wife swapping and licentious fantasy. Six characters reside in a household: an incestuous father; an acquiescent mother; a philandering son; the son’s wife, who is sleeping with her father-in-law while tempting her husband’s best friend; and a cousin who pursues the friend and father, all while sleeping with the son.
