Undercurrent Review: A Solid Pick for Dutch Action-Thriller Fans

This Undercurrent review starts with a simple promise: a small island, a big secret and a heroine caught in the middle. Klaas de Jong's Dutch action thriller (original title EB) trades city skylines for windswept coastline and tidal flats. It is a modest film, but it has a clear hook and a pulse.

Undercurrent Review: The Story So Far (No Spoilers)

The Undercurrent plot follows Lynn, an ambitious ecologist who comes back to Ameland, the Dutch island where she grew up. She expects fieldwork and a quiet reunion with familiar faces. Instead she stumbles onto a drug smuggling route running through the landscape she knows so well.

That discovery sets up the central dilemma. Lynn can expose what she has found, or she can protect the people close to her who may be tied to it. The film builds its first act around that tension and keeps the stakes personal rather than global.

What Works in Undercurrent

The setting is the film's best asset. Ameland feels isolated, exposed and slightly eerie, which suits a story about secrets hiding in plain sight. Tides, dunes and weather give the action a physical backdrop you rarely see in Dutch genre cinema.

The premise also gives the film a sharp moral engine. An ecologist is trained to notice what is out of place, and that makes her a believable person to spot the crime. Writer Lars Boom keeps the setup lean, so the film gets moving without long detours.

At 111 minutes, the pacing is mostly steady. Here is what stands out:

• A fresh, atmospheric island location

• A heroine whose job fits the plot

• A personal conflict rather than generic gunplay

Undercurrent Cast and Performances

The Undercurrent cast is led by Vajèn van den Bosch as Lynn. She carries the film with a determined, guarded presence and sells the pull between duty and loyalty. It is the kind of lead role that needs to hold the screen alone for long stretches, and she manages it.

Juvat Westendorp plays Kevin and Mingus Dagelet plays Stefan, two figures from Lynn's world whose relationships to her drive much of the tension. Bart Harder appears as Visser, Jord Knotter as Boris and Mike Libanon as the police chief. The ensemble feels grounded and local, which helps the island feel lived in rather than staged.

Where Undercurrent Stumbles

The film's modest scale shows. The central conflict is clear, but a story about smuggling and divided loyalties can fall back on familiar beats. Viewers who have seen a few crime thrillers will often sense where a scene is heading.

Supporting characters also get limited room. Some of the people around Lynn work more as pressure points than as fully drawn individuals. A little more depth would have made her choices hurt more.

If you want something with more crime-world texture, our crime movie reviews offer plenty of alternatives. Action here is practical and measured, not spectacular.

Is Undercurrent Worth Watching?

Yes, Undercurrent is worth watching if you like compact, character-led action thrillers with a strong sense of place. It will not reinvent the genre, but it uses its location and its central dilemma well. Audience reaction so far is positive, with a TMDB score of 7.2/10 from 22 votes, though that is a small sample.

The Undercurrent release date was 14 May 2026. It is a Dutch-language film, so expect subtitles if you do not speak the language. Director Klaas de Jong keeps things tight, and the result is a watchable, unpretentious ride.
