After Lily lets herself into his home, Al takes matters into his own hands. Karen and Rob struggle to deal with Tom's behaviour, and Emma meets a medical student whose secret experiments have gone too far.

Al worries that Lily's latest move may have put his mother in danger, whilst Sid and Bear worry that Daniel is having a mid-life crisis. Jimmi helps with the death of a young woman at the university, but all is not what it seems.
