David Main is an ambitious, dynamic and highly capable young solicitor who, having gained valuable experience in London, returns to his native Leeds to establish a new practice. Driven by a thirst for success, Main seeks out the most lucrative cases, but is also a man with a conscience who often acts for the most vulnerable and underprivileged. While his occasionally impetuous approach can take him into difficult legal waters - to the distaste of his more reserved and cautious Leeds partner Henry Castleton - Main's acumen and resourcefulness rarely fail him. John Stride stars as David Main, alongside Anna Palk as his efficient and attractive secretary, Sarah Courtenay; Peter Bowles, Diana Coupland and Peter Jeffrey are among the guest stars in this second series of the immensely popular drama from Yorkshire Television. The Main Chance ran for four series between 1969 and 1975, and Series Two, originally screened in 1970.
