Island Crossings - Season 1

Ardrossan staff deal with delays and queues due to an engine fault as the Kilbarchan Pipe Band are among competitors and spectators trying to attend the annual Brodick Highland Games. In Mull, 12-year-old Oscar heads to the mainland where he'll spend weekdays away from home for the first time at secondary school.

Twenty new apprentices join the ranks of ferry operators Caledonian MacBrayne and take a tour of the MV Caledonian Isles, where they get a glimpse into living and working at sea. It's the final cattle sale of the year on the Inner Hebridean island of Tiree and local crofters are getting their cattle ready for market.

Weather and mechanical issues cause havoc across the network, jeopardising thousands of pounds in fresh Barra shellfish, and there is a hotly contested oyster competition.

CalMac engineer Fergus races in the annual Mull Rally, and CEO Robbie gets hands-on in the MV Caledonian Isles engine room as things start to go wrong.

A freight backlog in Stornoway has area operations manager Fiona struggling to keep supply lines to the isles open, and CalMac trainee sisters Tanya and Natalie go to sea.

One ferry's overhaul costs £2.8 million, but unforeseen issues could result in an extended dry dock with huge implications for the network and island communities.

Dry dock delays and breakdowns cause chaos across the network, triggering a crisis meeting at HQ. On Islay whisky freight, tourists and locals vie for space on the ferry.

Kerrera Island's annual triathlon is at risk due to bad weather weather, while a folk legend explains why being a binman on Barra makes him proud.
