Season 1

Mogul strikes oil in the North Sea and everyone is sworn to secrecy. So when the story leaks to the press, executive Brian Stead wants the culprit sacked. Peter Thornton is sent to the rig to discover which rigger talked.

Robert Driscoll is sent out to take over negotiations for an important Middle East oil concession after the mogul representative has been killed in the desert. Driscoll antagonises the men on the spot, particularly the area manager Charles Andrews, who thought that he should have had the job.

Wildcat drilling is a calculated risk for Mogul. But for an African executive backing his own judgment it brings still greater hazards.

Heavy drinking Tosh Brinkwater has married late in life and starts to regret the decisions he has made and needs to settle down. Stuck in a boat in Egypt he decides to jump ship and head home but gets no further than a brothel.

The desert is like the sea. It takes possession of a man's soul. For a young geologist seeking to prove himself it is exciting. But like the sea the desert is dangerous.

Motor racing means excitement; it also means danger. Driscoll faces personal risk when he opposes Stead and tries to steer Mogul into Grand Prix racing.

Trouble erupts around Mogul's new North Sea rig when a few unguarded words open old wounds in a Tyneside shipyard.

The glittering world of advertising is a wonderful dream for Miss Mogul, Sandra Spratt. But others have a different view - and create a headache for Derek Prentice and Mogul.

Prejudice has deep roots. Driscoll is involved in an explosive situation in northern Canada when Mogul takes an Iroquois Indian for an important job.

Freedom is very desirable. But when Peter Thornton envies the life of a Mogul tanker driver he finds that no man is as free as he seems.

A beautiful girl and a heart attack combine to make Brian Stead want to retire. But attacks from within Mogul rouse his fighting instincts and complicate his decision.
