Synchronic is a 2019 American science fiction horror film directed and produced by Justin Benson and Aaron Moorhead.

Synchronic stars Anthony Mackie and Jamie Dornan as paramedics who investigate a series of inexplicable deaths and their connection to a new designer drug.

Steve, a womanizing New Orleans paramedic, and his devoted partner, Dennis, face a string of deaths all linked to a new designer drug, Synchronic.

When Steve is accidentally pricked by a contaminated needle during a call, tests reveal not only possible infection but also an aggressive cancer in his underdeveloped pineal gland.

In September 2018, it was announced Jamie Dornan and Anthony Mackie had joined the cast of the film, with Justin Benson and Aaron Moorhead directing.

It is mentioned that the titular drug was synthesized from a red flower grown in the California desert, referencing the plant smoked by members of a commune in the film The Endless.

The site's critics consensus reads: "Synchronic sets off on an intriguingly idiosyncratic journey that should satisfy fans of Aaron Moorhead and Justin Benson's earlier work.

"[9] Metacritic reports a weighted average score of 64 out of 100 based on 23 critics, indicating "generally favorable reviews".
