'High Seas' on Netflix: Everything You Need to Know About the Spanish Mystery Series

If you’re looking to get lost in an old school mystery, then Netflix has just the series for you. High Seas, also known by its Spanish title Alta Mar, is an Agatha Christie style whodunit set on a gorgeous ship filled with people that are just as beautiful as they are mysterious. The creators behind the new series put painstaking detail into recreating all the glitz and glamour of the 1940s, and now you can escape into all 8 episodes of Season 1.

But considering Netflix releases a whole lot of new shows every weekend, it’s possible High Seas has drifted under your radar! Don’t worry–if you’re looking for the basics about High Seas, we’re here to steer you in the right direction. Here’s everything you need to know before jumping into the deep end.

**What is High Seas on Netflix about?**

This murder mystery series from Spain is set on a transatlantic ship in the 1940s. The series focuses on two opposite sisters, Eva and Carolina, as well as a ship full of colorful characters all hoping to find romance and adventure during their journey from Europe to South America. What they end up finding, however, is a dead body–a woman that wasn’t even on the passenger list! Trapped on the boat with a murderer, every passenger becomes an amateur sleuth while also fighting to keep their own personal secrets hidden.

The series is the latest from Spanish showrunner Carlos Sedes, the director behind previous international hits like Velvet, Grand Hotel, and Netflix’s Cable Girls.
