Plot
Haakon Haakonsen (Stian Smestad), a young Norwegian boy in the 1850s, becomes the sole support of his family as a cabin boy on a ship after his father is injured. Jens (Trond Peter Stamsø Munch), who was a shipmate of Haakon's father and a friend of the Haakonsens, agrees to be a "sea daddy" to Haakon, teaching him seamanship and acting as an older brother during their voyage.
At first, Haakon has a difficult time adjusting to life at sea, but eventually earns the respect of his shipmates. After shore-leave in London, a British naval officer, Lt. Howell, joins the crew ostensibly to provide protection from pirates. Unbeknownst to the crew, he is actually a notorious pirate named John Merrick, who has murdered the real Howell and taken his identity. Haakon learns that "Howell" has secretly brought guns onto the ship, and Howell attempts to persuade Haakon not to say anything about the guns to the captain.
After the mysterious death of the admired captain (who had been poisoned by Howell's first mate), Howell assumes command. Upon arriving in Sydney, shore-leave is abruptly cancelled and a suspicious new batch of sailors come on board. After departing Australia, Haakon discovers a stowaway (Louisa Milwood-Haigh) named Mary who turns into a love interest. Work on board the ship soon becomes terrible for Haakon, Jens, and the original sailors, which intensifies when the new captain finds Mary and demands whoever has been fraternizing with her to show his face. Haakon admits responsibility, and the captain sentences him to be lashed with the cat o'nine tails. Jens protests, saying that whipping Haakon would be an effective death penalty, to which Howell orders that Jens will administer the punishment to Haakon instead of Howell. However, the court martial is interrupted by a terrible storm that damages the mainmast, then sinks the ship. Haakon manages to rescue Mary from the brig but in the confusion is separated from the crew and wakes alone up on a deserted tropical island.
After searching the island, Haakon discovers treasure as well as wanted posters for an English pirate named Merrick (Gabriel Byrne), who looks identical to Howell (in the first scene of the film, the real Howell was murdered by Merrick, who then stole Howell's identity). Haakon discovers that the suspicious shipmates (i.e. the new batch of abusive shipmates who were brought on after Merrick's captaincy) are really pirates, who stored the treasure during a hot pursuit from naval forces, and will soon return to the island to extract their loot.
Following a self-training with a sword and gun, Haakon manages to use a horn when a gorilla attacks. This makes the gorilla docile, who then starts to befriend Haakon, behaving like a pet. Haakon devises a set of booby traps anticipating that the pirates will soon return for their treasure. Although Haakon adjusts to the island, he misses Jens, and more so his family back in Norway. One day, Haakon sees smoke from a distant island and tries various attempts to get there on a raft of his own.
Upon successfully arriving there, he finds a village of natives doing a night dance. Haakon encounters Mary wearing a native dress and native shoes in the middle of an altercation with several of the natives. Misinterpreting the situation, Haakon reveals himself and frightens the natives with a gunshot until he backs into Jens, who explains that the natives are peaceful and saved his and Mary's lives. The reunited trio happily depart for Haakon's island the next day.
Shortly thereafter, the three friends witness the arrival of the pirates along with Berg and Steine (Knut Walle and Harald Brenna), two of Jens' friends who survived the sinking ship and are being held prisoner. After Haakon's traps fail to work, he quickly devises a plan to save their friends. At night, Mary sneaks aboard the ship and frees the remaining crew who manage to overpower their pirate guards and retake the ship. Meanwhile, on land, Haakon and Jens manage to distract the pirates long enough to free Berg and Steine and narrowly make it back to the ship, stranding the pirates on the island. Haakon, Jens, Mary and the liberated crew return to their native Norway. Each man keeps a small share of the treasure, with Haakon deciding to use his share to get his impoverished family out of debt.
Back home in Norway, Haakon reunites with his family and introduces them to Mary. His parents agree to take her in until she can reestablish contact with her own relatives.
