Sandra Croft gets drunk because her boyfriend has left her and accidentally sets fire to her apartment. Luckily she is saved without any injuries by PC Rowan. The incident makes Sandra fall in love with Nick, but she turns resentful and revengeful when he does not return her affection. Greengrass has a new scheme: guided tours and bird watching! But he soon finds out that there is more to it than just setting up a shelter as a hide, handing out copied old maps and then collect the money.

Steve and Amy are two of a group of squatters who move into Geoff Lawson's empty cottages on Oddy's Field. When Lawson hears about it he tries to get the squatters out, but that is easier said than done, and the squatters make Lawson look like a fool time and time again. When not even a court possession order helps three thugs break into the cottages to remove the squatters by force. Lawson is the prime suspect, but when the police catch the bullies they say they were hired by a woman. PPC Nicholson feels he is kept out of the investigation, follows up on a lead and questions Amy, who is very pregnant with Steve's baby. As expected Nicholson only screws things up - and triggers off the birth of Amy's baby.
