Dr. Ormerod is furious to discover the police have launched an investigation into his wife's death, and reveals in a heated outburst that she was planning to leave him at the time of the accident. Bad news strikes a family when it emerges a couple's son has developed a hereditary heart disorder, a mother-to-be suffers kidney failure during childbirth and hospital porter Ken Hopkirk needs an operation after injuring himself while lifting a piano. Romance blossoms for Dr. Goodwin and student nurse Samantha Beaumont, and Lizzie Kennoway's driving lesson ends in disaster when she slams into the back of Mr. Harper's parked car.

Ormerod faces a taxing time when a prison van overturns on the moors. The driver is killed, a guard is seriously injured and one of the convicts escapes, while the others are rounded up and taken for treatment at the hospital, where Ken Hopkirk recognises an old friend. Goodwin fails to diagnose a serious case of post-natal depression - an error which almost ends in tragedy when the mother is found standing perilously close to a cliff-edge - and student nurse Samantha Beaumont discovers she has an unexpected love rival.

Sister Brigid is concerned about the head of her convent who is refusing treatment and Jill hears from Samantha.

Dr. Goodwin faces the pressure as rumours about him frantically circulate the hospital and when Dr. Weatherill passes on some important news, he wastes no time in using it to set the record straight. Nurse Taylor's happiness about her future with Frankie is sensationally shattered as the extent of his dishonesty is revealed, while Matron is shocked to see a familiar face on the ward.
