From Netflix:

After a terminally ill secret agent retires to spend his remaining time with his family, he’s asked to complete a dangerous last mission in exchange for an experimental drug that might save him — if he can survive its hallucinatory side effects.

At his current age of 59, Kevin Costner in this film does indeed look like a tired and sick aging man. But here he is as much Kevin Costner, neither better nor worse, than in any of his other films. It is amazing how he never misses a shot with his many weapons.

So what makes this story different from any other “secret agent lethal assignment” story?

• He is dying of a brain cancer.
• He has ignored his wife, from whom he is separated, and daughter throughout his career. Now is his chance to reconcile.
• Not too terrific actress Amber Heard, playing supposedly sexy Vivi Delay, trades one last killing assignment for a series of experimental shots that may cure Harrison.
• One side effect of the drug is that whenever Harrison’s heart beats too fast (think “Shootout at the OK Coral”) he gets dizzy and nearly faints. This effect is annoying when he is confronting each of the really mean bad guys.

Details were clever enough to keep me interested.
