Edward and Jennifer return from holiday, anxious to acquaint Mary with their marriage plans but find her collapsed with another heart-attack. The Hammonds prove their ability to rally round in a crisis. A good time for Riley’s wife, Gwen, to lend her assistance.

As the debate about going public begins, manoeuvres are made for control of the board. In readiness Brian meets merchant banker Martin Farrell, while Edward sounds out Riley.

The first steps are made for the Hammonds to go public. Farrell prepares the investigations, and in the process notices the company’s organisational weaknesses.

Riley and Farrell join the Hammonds’ Board. At once Brian and Riley come into conflict. But Brian’s behaviour is really a reaction of his worsening relationship with Ann.

Edward and Brian attend a lunch in the city with Paul Merroney, a merchant banker, to launch Hammonds as a public company. Edward begins to act the role but Brian looks far from the part.

Brian and Ann apart face the problems of loneliness; by contrast Martin Farrell and Jennifer enjoy dinner together. Meanwhile the Hammonds are invited to a shoot – on business.

The procedure for making Hammonds a public company get underway, and the directors attend a shooting party to meet Sir Neville Henniswode – the chairman of their merchant bank.

A local petition protesting about Hammonds lorries coincides with the firms moves to go public. But it is not only the residents the Board has to face.

David, with the company’s sponsorship, has his first experience of driving in a race. In an atmosphere of tension and excitement, Jill watches his performance.

The men want a share of the fat profit they think Hammonds will make when they go public – if not, they may strike at a vital moment. Brian is involved in a serious car accident.

Edward meets prospective business-world share holders, but his frankness causes a set back.

The company goes public – in an atmosphere of tension the share issue is placed on the market.

Edward fights for survival as Chairman and Managing Director of Hammond Transport Services Limited – and everyone’s loyalty is tested to the full.
