Prime Video’s latest 8-part mystery begs to be devoured in one night

Here’s a situation for you: You find out one day you’re the proud owner of a whole island. Not just your name on a beach hut – an actual island, in Canada, with a big scenic lake and corners that look like they’re holding a family secret or two. That’s the setup for Sterling Point, the sort of bingeable family mystery arriving on Prime Video tomorrow. Not to pile on, but between Reacher getting a fourth series, that Neagley spin-off in September, and the clever Off Campus, Prime’s on a bit of a roll lately. Sterling Point is slap in the middle of all this, and I’m already clearing the calendar.

Sterling Point's entire first series arrives on Prime Video 5 August 2026.

The Big Summer Inheritance

So, what’s the deal here? Sterling Point follows Annie Jacobson (Ella Rubin), your average teenager until she and her twin brother Connor (Keen Ruffalo, yes, Mark’s nephew) learn they apparently own a Canadian island left to them by their late grandfather. Standard teen summer, find yourself somewhere remote, except now Annie’s got new neighbours – and some fairly big questions about her own family tree. The usual excitement and nerves get amped right up when Annie runs smack into Ramona (Amélie Hoeferle), a girl who, if you squint, could be Annie’s sister. (Hint: she is.)

There’s a proper ‘wait, what?’ moment early on, when Annie calls her brother and explains she just met a girl on the island who looks the absolute spit of their mum, and claims the late granddad was her relative too. Simple lakeside holiday? Absolutely not; there’s a family mystery begging to be solved.

Cast, Vibes, and a Bit of Mystery

The main cast leans solid – Jay Duplass shows up as Annie’s dad, Missi Pyle pops in, and Jeffrey Dean Morgan, world’s most typecast hard man (Negan in The Walking Dead, of course), gets a very different role this time. Early signs point to him actually behaving like a normal man for once, which, frankly, is a relief.

The first series comes in at a compact eight episodes, all dropping at once. I’d honestly struggle to wait weekly for this sort of family-revelation genre, so hats off to whoever approved the binge release. With a plot about twins, inheritance, and an emotional tie to a late mum whose own life on the island is central to things, it could go either way: neat one-off, or recurring every summer if the numbers stack up. No word on a second series – it’s all down to how it lands this week.

• Sterling Point is set on Lake Muskoka, for those who track Canadian settings, which is basically cottagecore central. If you caught Every Year After (set in Barry's Bay), you’ll know the look: dreamy lakes, canoes, hints of drama lurking in the bushes.

Behind it all you’ve got Megan Park, who’s properly making a name after The Fallout (the bananas-good Jenna Ortega drama about trauma) and My Old Ass (that one where a young woman literally meets her future self, but without a moral lesson shoved down your throat). Both were a cut above the usual, with mental health and tough choices at the core, so it's a fair bet Sterling Point will bring real heart and a twist or two.
