In this wildly imaginative and satirical comedy, a newly retired couple picnics on a beach and squabbles about their life together when they are interrupted by two human-sized, English-speaking lizards. Are the newcomers an evolutionary miracle, or a threat? And which couple is the greater risk to the other? As the two pairs begin to communicate, they come uneasily together, discovering how transitions in life can spark terror and restlessness in any creature of habit. A sparkling fantasy of growing up and growing old, fear and adventure, love and laughter.
