 Sarah and Reg arrive at mum s house for the weekend so that invalid mum s care-giver, Reg s sister Annie, can get away for the weekend. But Annie ends up staying, their brother-in-law Norman shows up unexpectedly, and not long after, so does Norman s wife Ruth (Annie and Reg s sister). Sarah tries her best to organize a family dinner for the five of them plus Tom, a slow-witted neighbor whom everyone expects to propose to Annie. Sarah can t get much cooperation and doesn t realize that Annie had planned to sneak off with Norman. Norman is incorrigible, Annie is caught between Tom and a fling, mum is upstairs demanding attention, and there aren t six proper chairs.
