Today an oil worker with a severely injured back is helicoptered off his rig, miles off shore, and brought to the Gilbert Bain Hospital.

The team have to use all their skills and resources to stabilise and diagnose him before deciding if he can be treated on Shetland or if he'll need an air ambulance transfer to the mainland.

Cameras follow a GP with Britain's most unusual commute, as he takes to the skies to carry out a clinic on Fair Isle, the country's most remote community. With no full-time doctor or nurse on the island, the residents here rely on his monthly visits.

And Eddie, a keen motorcyclist, comes into the hospital after colliding with a seagull while riding his motorcycle at speed. His Shetland sense of humour is intact, but Dr Lalla and his team are concerned about how much damage the bird may have done to his neck.

Today the show takes a closer look at life for Shetland's new and expectant mothers.

In the Gilbert Bain maternity department first-time mum-to-be Caitlin has come in, as she's eight months pregnant and can't feel her baby moving. And a woman, 10 days past her due date, has to be flown from Shetland to the mainland for specialist assistance giving birth.

Away from the hospital, cameras follow a midwife from Aberdeen who's recently moved to the islands and is struggling to find her way around while making house calls to Shetland's newest mothers.

And two young girls visit A&E, one having fallen off her Shetland pony and breaking her collarbone and another with a badly injured arm following a trampolining accident, meaning the staff at the Gilbert Bain, who are not specialist paediatricians, will have to use all their skills and training to treat them.
