The sea has a special relationship with the coast of eastern England. It brings, gives - and takes away. Some of the things, including people, which it snatches never return. Others are beached far down the coast. From earliest times humans have tried to preserve the land from the waves. All such attempts ultimately fail.

Alan Franks' play is dominated by the sea. Its characters live beside it; some have lost family to it. The action spans three decades, from the austerity-constrained Fifties to the onset of the go-grabbing Eighties. When we first meet her, Miriam is a teenager from a fishing family whose relationship with undergraduate Billy disintegrates even before she falls pregnant.

Having an illegitimate child was a shameful matter in 1953. The mother-to-be would be packed off to relations or an institution at the other end of the country and never allowed to forget that she had brought shame on her whole family. Many children were taken away soon after birth for adoption. Which is what happens to Miriam and her daughter.

Fast forward to 1979. Miriam has been trying to trace Miranda, without success. Billy has becomes one of those punditing presenters of television heritage programmes. Miranda, herself now working in media land, with her sights set on a not-too-interested colleague, has been using changes in legislation to track down her birth mother.

Happy ending, then? No, not quite. There's more to this play than its plot. Just as the tide comes in with a succession of waves, rippling the sand and obliterating tracks in it, so the short scenes overlap in time and emphasis.

Four players take all the parts - Anstey Thomas as the older Miriam, her mother, aunt and a variety of would-be do-gooders, Eleanor Harley as the young Miriam and Miranda, Simon Bubb as the young Billy and Miriam's simple cousin Roger and Patrick Knox as Billy's corrupt, social-climbing father, not-so-good-doer doctors and vicars, then (chillingly) as Billy made good - in his father's image air-brushed for the Thatcher era.

If you've never seen an Ivan Cutting production for this tight-knit touring company (Eastern Angles), whose stagings rely less on scenic values than on speech, movement and the creation of an almost-indefinable atmosphere, this is a good place to start. You'll need to use your ears, instinct and intelligence as well as your eyes. But isn't that what theatre's all about?
