A 15 year old schoolgirl has given birth to an illegitimate baby. Within a week of the birth, the body of the baby has been found buried in the girl's back garden by police acting on a tip-off. The schoolgirl's father (the baby's grandfather) has been charged with the murder of the baby after it was discovered that the infant had been strangled.

The previous day ended sensationally with both Dominic Collins' wife and daughter confessing to killing the baby. Barrister Helen Tate accuses Mary of researching the Infanticide Act in bid to get her father off a murder charge.
