Siobhán's a marine biology student who prefers spending her days alone in a
lab. She has to endure a week on a ragged fishing trawler, where she’s
miserably at odds with the close-knit crew. But out in the deep Atlantic,
an unfathomable life form ensnares the boat. When members of the crew
succumb to a strange infection, Siobhán must overcome her alienation and
anxiety to win the crew’s trust, before everyone is lost.
