As archaeologists are a type of detective it makes sense for this show to be part mystery, part fantasy and all adventure. The writers also manage to find ways in each episode to show how history is all around us literally by having the finds show up everywhere from the seashore to parkland. They also makes sure we understand how the past and present interconnect. Whether it's somebody looking to history to further their own goals by twisting it to suit their needs or how our lives were shaped by events which happened thousands of years ago, they manage to make us understand we ignore the past at our peril. What's even better is they do this through the action and plots of each episode. You never have the feeling they are lecturing you, instead the shows offer examples of how important it can be to know history and understand it.
Aside from history we also learn a lot about the techniques and methods used in archaeology. A mixture of painstaking detail work and high tech science go into helping our team uncover the secrets stored in a fragment of wood or a piece of cloth. From the site of a mysterious battle field which saw the slaughter of Knights Templer to the remains of what seems to be a slave ship in a tidal estuary they are able to take what looks like scraps and recreate events that happened hundreds if not a thousand years ago. No secret, no matter how well hidden, is safe and no mystery will stay unsolved for long when our team puts their minds to it.
Unfortunately there turns out to be any number of powerful people who either would like certain secrets left buried or want mysteries solved for their own nefarious purposes. While it does require some suspension of disbelief on the audience's part, somehow each find Magwilde and her team work on, ends up having a bearing on the mystery surrounding what happened to Magwilde's mother. Her mother was being used by a very powerful group of people in an effort to find one of England's most potent artefacts, Excalibur, the supposed legendary sword of King Arthur.
Almost against her will, Magwilde finds herself being drawn into the hunt for the sword as well. As more and more evidence accumulates pointing to its possible whereabouts she also begins to receive mysterious messages and packages encouraging her and offering help. As each episode passes, and they uncover yet another link from the past to the sword, the mystery within the mystery grows. Who are these people offering help? What did her mother discover that ruined her reputation and cause her to attempt suicide? Will Magwilde go down the same path of self destruction, or will she be able to find the solution and come out the other side?
