Unemployed and unattached, Tom Chadwick is surprised when he is bequeathed an old chest of curios by his great-aunt Victoria, who he and his sister Bea don't remember ever meeting.
He finds an old black-and-white photo in the chest that his father Keith believes is Tom's great-grandfather Harry. With the help of his avuncular neighbour, Mr. Pfister, and his old school friend Pete, Tom tracks down a rather unusual expert in the field of antique photos called Neville St Aubrey, who discovers some very intriguing and revealing information about Tom's ancestor.
Meanwhile, Pete tries to get Tom's love life back on track by setting him up with a 'model pretty' date. He's just not sure what kind of model.
