The Billionaire: Part 1

Plot
Albert Gordon, an American business tycoon living in Britain as a wealthy patriarch, is found murdered. American lawyer Michelle Thomas, who works for him, finds his body. Eric Gordon (Greg Evigan), one of his two sons, is found guilty of his murder. His sister Laura believes in her brother's innocence and sets up a mock trial, hoping it will lead to a retrial. Matlock travels to England to represent Eric. The mock trial is exactly like a real trial, in the old Bailey, with the original prosecutor and a judge who came out of retirement.
