Apart from the big trial, there are a few storylines going on.
The main farming families are David and Ruth Archer and their children, Pat and Tony Archer (Helen's parents) and their children, and Brian and Jennifer Aldridge and their children. Jennifer, Tony and Lilian are siblings. David has three siblings - Kenton who runs the pub, Shula who runs the stables and who lied to protect Rob when he attacked the hunt saboteur, and Lizzy, who's late husband owned the local stately home.
Lilian is having an affair with a man called Justin, who has just employed Rob to run his farming business, which will involve being the boss of Adam, who is Helen's cousin and married to Ian, Helen's best friend.
Brothers Toby and Rex Fairbrother have recently moved to the village to set up a goose farm. Rex is responsible, Toby is a twat. We keep hearing about some mysterious way in which Toby cocked up 'in Brighton'. Rex is desperately in love with Pip Archer, the daughter of Ruth and David Archer who let the boys their land. Pip has been stupid enough to have a brief fling with Toby, but seems to have sent him packing.
The Grundy family are facing homelessness again (this happens to them about every other year). This is Eddie (chancer) and Clarrie (salt of the earth) Grundy, and Eddie's very elderly dad, Joe. There are also Eddie and Clarrie's son Ed, his wife Emma, and their children. Joe is determined to die in the place they're currently living in, which is the old farm they lost when they went bankrupt many years ago. (It was bought up by the wealthy Oliver Stirling, who has a fondness for Ed and so let them live their while it was empty for a few months.)
Both Clarrie Grundy and a woman called Susan Carter work for Pat Archer at her organic dairy, making yoghurts and ice cream. Susan is a terrible gossip and the fact that she's been in prison herself doesn't stop her slagging off Helen.
Kirsty, Helen's best friend, was engaged to Tom, Helen's brother, but he jilted her at the altar. Luckily, she appears to have forgiven him...
That should keep you going for a bit.
