DOC MARTIN Mondays, 9pm on ITV1

Caroline Catz returns as Louisa Glasson.

This new series begins with Dr Martin Ellingham struggling to cope with new fatherhood, as he embarks on a new chapter of his career, which is set to take him away from the small Cornish village.

Sleepless nights take their toll on the doc and his partner Louisa Glasson, and put their shaky relationship under strain. Can they make it work this time round?
