Skjærgårdsfeber follows boating enthusiasts in, on, and around the Oslofjord. The archipelago is where summer dreams meet reality, the sea spray is fresh, and the boaters' maneuvering skills vary dramatically. In Archipelago Fever, every bay, every cape, every headland and every harbor is explored – from idyllic gems to places where you should rather not dock. There is sun, rocky shores, swimming, screaming seagulls and just the right amount of drama.
Snefrid and Erik are preparing a boating holiday to celebrate their 35th anniversary. Aksel uses the archipelago for his great passion, butterfly hunting. Strict captain Toni takes his buddy and boating novice Yousef on a boating trip in the inner Oslofjord.
DJ Donald, one of the capital's most experienced and colorful disc jockeys, has big plans for the summer. Snefrid and Erik continue their boating vacation: They fish for crabs, drive a boat, look for animals on Hovedøya, and are fascinated by a strange tree.
Toni and Yousef take a boat trip to Hovedøya and have a lovely day in the archipelago. We get to know the talkative harbor manager Christian at Kongen Marina, who has many irons in the fire, and fortunately, assistants to do the job.
After a successful test trip, Snefrid and Erik go to buy their own boat and head towards Tjøme. DJ Donald decides to entertain the beachgoers at Sørenga with a concert from a small motorboat.
Tore takes his daughter, Lene, with him to teach her a thing or two about sea life, which leads to Tore almost drowning twice. Lars and Stella head north into the Oslofjord, having a lovely day on the boat, until Lars swallows a fly.
