The Sessions tracks the emotional journey he made with the help of his priest, Father Brendan (William H. Macy), and his sex surrogate, Cheryl (Helen Hunt).
Father Brendan's initial shock at what he is hearing is soon replaced by a deep understanding of Mark's turmoil.
Although Mark has severe physical limitations, he doesn't lack the ability to make an impression on women, particularly his carers.
And Cheryl is not immune to his charms either.
Married with a child, Cheryl is a therapist with a special ability to help those in need.
In surely her most challenging performance, Hunt lays herself bare in front of the camera and totally embraces her role.
The Sessions has a rare combination of a compelling story with performances of true class.
The three stars deliver on the story of a remarkable man.
