Addiction has been on the big screen for as long I can remember. Oftentimes, the films focus on those who are addicted. Rarely do they focus on the lives of those around them.

The recently-released “Four Good Days” focuses on the mother of a junkie. Deb (Glenn Close) is the mother of Molly (a barely recognizable Mila Kunis), a drug addict who has been in and out of rehab more times than they can count. When we first see Molly, she shows up on Deb’s doorstep like a stray dog. She’s stick-thin and pockmarked with teeth rotting out of her head.

At first, Deb resists Molly, who asks her mom to take her back to rehab. Molly, however, will not leave her old home and sleeps on the stoop all night. Finally, Deb relents and offers her a ride to rehab to see if she’s serious this time around.

If you are a parent, your heart will break for Deb. She wants to help Molly. However, we quickly learn that Molly has stolen cash, credit cards, jewelry and guitars from her mother’s home to finance her addiction.

At the center of the film’s plot is an opioid antagonist, an injection that will reduce heroin cravings for 30 days. However, Molly will have to get through four days following her final day of detox to qualify for the treatment. Get it? “Four Good Days.”

At the outset of rehab, Molly struggles mightily. She twitches, scratches and smokes cigarettes nonstop. To Deb’s credit, she takes Molly back in — again — and encourages her to get clean. It is really heartbreaking to watch Deb blame everyone — with the exception of Molly — for the mistakes that were made along the route to addiction.

We find out that Molly got hooked on pills as a teenager. The pills were prescribed as the result of a knee injury and they sent her down an ugly path. We also learn that she has two children that were taken away as a result of her addiction. To say that Molly’s life is a mess is an understatement.

The film mostly centers on Deb and Molly’s relationship, or lack thereof. Deb is no longer with Molly’s natural father and is remarried to Chris (the always solid Stephen Root). Their relationship is rocky. Chris adores Deb, but her inability to cut ties with Molly wears on him. He’s retired and spends his days reading too much news and strumming away on a guitar.

At times, “Four Good Days” feels like a television movie, which is a shame. The filmmakers opted to go for some cheap drama rather than stick to the core of the story. In one scene, Molly goes to a flophouse to help a fellow addict, which seems forced. In another scene, Deb forgets her wallet at home and races back to make sure that Molly hasn’t cleaned her out to buy more drugs.

While those scenes come across as trite, there are truly some tough scenes that will tug at your heartstrings. During one such scene, Molly talks to a classroom of high school students and explains her battle with addiction. She goes through her life, blow by blow, all with her mother watching. After speaking to the class, Deb tells Molly she’s “proud of her.”

As she often does, Close really pumps life into the script. And Kunis shows off her acting chops by playing Molly. She’s come a long way since her “That 70s Show” days.

While “Four Good Days” won’t win any awards, it is a solid film. The performances of Close and Kunis are worth watching.

“Four Good Days” is rated R for adult language, drug use, sexual content and adult themes. It is available on Xfinity OnDemand, Vudu and iTunes.
