Roughnecks

The crew visit a neighbouring rig for the annual quiz night. Pitted against Osprey's Ceefax is the arrogant Aussie know all, Joe 90 (Ben Mendelsohn). Meanwhile Tessa makes Charlie's widow's dreams come true...thanks to a little emotional blackmail on Drew. Cinders survival refresher means the Osprey is without a chef, but Village surprises everyone with his Italian cuisine.

Shore leave for the Roughnecks; Hilary decides to join Ian for some hillwalking but a mistake with the hotel booking means they must share a room. Tom's daughter Heather is getting very close to Chris, despite Tom's reservations, and there's heartache for Archie when he learns his estranged wife Jean may have been assaulted by her new man, Bob.

A female reporter visits Osprey Explorer keen to get a story, but ends up getting under Chris' skin. When it becomes clear her intentions are to get the dirt on how Charlie died, she finds herself out in the cold. Tessa breaks her foot putting the crew's bonus of a mini portable colour TV each into jeopardy. Meanwhile Chris and Heather get closer.

Chris and Heather return from Spain and announce their intention to marry. Tom is furious and lashes out at Chris, but their differences must be put aside as they head offshore. Ian's concerns over safety on the rig proves justified when a crisis develops and several of the crew are evacuated by helicopter. Just when the crisis seems to be averted, further disaster strikes...

Grief, trauma and suspicion lie in wake for the crew following the helicopter crash. The finger of blame points to Chris, as an investigation into the disaster gets underway, whilst Hilary takes the news of Ian's death hard. On the mainland, Chris and Heather tie the knot.
