Bryon, a murderer in the present day, steals a time-travel device from a cop in a secret
government program so that he can go back to rescue his ten-year-old self from an abusive
father. The kidnap plan succeeds, but the father gloms onto the pursuing cop as she returns
to the future, and together they chase after Byron (old) and Byron (young) with lots of
gunslinging.
— Michael Main
He’s kidnapped himself, his younger self. It’s difficult to understand, but crap like
this happens.
