“H+” is designed to be watched in any order, as each episode takes place in a different time and space, allowing viewers to stick with the main storyline in the parking garage first if they choose. This storyline begins with Julie Martin (Nikki Crawford) and her husband driving to the airport “5 minutes before it happened.” As they are making their way out of the parking lot, all hell breaks loose as the system crashes and people begin dropping like flies, cars and planes crash, and the automated sprinkler system goes off all over the garage. Only Kenneth Lubahn (David Clayton Rogers) seems to know what’s going on, telling the others they should be safe so long as they remain on the lower level of the garage where the signal is out. Med student Francesca Rossi (Lela Loren) works with him to save Julie’s husband, who has also fallen victim to the virus despite being in the same underground area as the rest of the survivors.

Meanwhile, the series flashes back to Helsinki, Finland, “7 years before it happened,” where Digital Crime Unit officer Topi Kuusela (Samuel Vauramo) begins to fall for Manta (Hannah Herzsprung), a mysterious target he has been assigned to follow. It is unclear so far what exactly her connection is to H+ Nano Teoranta, the company that manufactures the implants, but with an estimated 48-episode run, it is clearly just getting started. The first 14 episodes are available now on YouTube, with new ones premiering on Wednesdays. It’s hard to tell so far if “H+” will live up to the promise of its premise, but its high production values, mysterious time-jumping narrative style and intriguing, multinational subplots make it seem well worth watching to find out.
