In a futuristic world where people are addicted to virtual realities,a cop who disapproves of such technology must plug himself in to save his only son when the system is hacked and threatens to kill all the people connected to it….only to find out his son is the mastermind behind the attack.

this is really good. start your outline/first draft right now. i actually wasn't hooked until the "son is the bad guy" twist so i say leave it in the logline, but don't have it be the twist at the end. That basically boils it down to: "A technophobic detective tries to save his son from a hacker threatening millions of lives" (if you take it out) or "A technophobic detective learns that his son is a hacker threatening millions of lives." (if you leave it in). I think the second one opens up more layers of conflict and growth for the protagonist but that's just me.

"technophobe" ...missed out on that.Giving away the plot twist in the logline was a silly thing.Will definitely keep those points in mind...Thank you so much.

will definitely keep that in mind next time.Thank you.
