Surrounded by rain, rivers, lochs and floods, three generations of memory and experience ebb and flow through this lyrical play.

No one's day is going to plan. Petal, Missy and Hen are on their way to the island of Iona, looking for a miracle. When their train is halted by floods, they are forced to stay at a B&B by Loch Lomond and contemplate different endings to their adventure. Jim, Guy and Sonny are also at the B&B. Guy is determined to make his own adventure, but Jim and Sonny's experiences make them equally determined to shelter him and stop history repeating.

But what happens when the dreams of the past start to catch up with the present - and shape the future? And how can we learn to dream them better?

Linda McLean's play Shimmer was first staged at the Traverse Theatre, Edinburgh, in July 2004.
