Loo Loo is a widow whose husband set up a trust in that the proceeds of their boarding house would give her an income. When Loo Loo takes a holiday with all the proceeds of the boarding house the trust must take over the day to day running. From here you are in for a great ride with such characters as Oscar, Never Say Die, Sixteen Tons, Leo, Ginger, and Ellie to name a few.
You feel for Charlie as he tries to keep the boarding house afloat, woo Ginger, keep E Farrington Ott happy (his boss), play matchmaker and keep one step ahead of Loo Loo.
