Argus (2022)

Time travel is real! Scientific prodigy Randall Patton has had a breakthrough
that allows travel through the timestream, which immediately led to the
creation of The Argus, the temporal law enforcement organization that polices
the time/space continuum. After an accident renders one of the members of
The Argus insane, he begins killing off the others - except they are all versions
of Randall Patton from various points in his own life! Who can stop Randall
but himself?
