The all-female version of the play Neville’s Island, Sheila’s Island sees four out-of-condition, middle-aged businesswomen set off on a team building exercise and succeed in becoming the first people ever to get shipwrecked on an island in the Lake District. Bound in fog, menaced by wildlife and cut off from the world, this perfunctory middle-class exercise turns into a carnival of recriminations, French cricket and sausages. What should have been a bonding process for Denise, Julie, Fay and Sheila turns into a muddy, bloody fight for survival. Because when night settles in, strange things happen out in the wilds. And what took place on Sheila’s Island that foggy November weekend none of this particular middle-management team would ever forget.
