Macdonald (Matthew Modine) survives a shoot-out after a heist gone wrong, but he has lost his memory and spends many a year in prison without knowing what really went on. Officer Sykes (Sylvester Stallone) was originally on the case and has kept a close eye on it as it went cold and colder. When Macdonald is sprung from prison after seven years, Sykes gets some help from the FBI to help track him down.
A key part of the success of 2015’s Sicario was Emily Blunt’s role, which provided a moral balance to the hard-hitting story. Her character does not return in Sicario: Day of the Soldado; the main reason for this, according the director Stefano Sollima, was that they explicitly did not want this sequel to have a moral compass. Unfortunately, it turns out that is exactly what makes this movie nowhere near as interesting as its predecessor.
