Daniel and Robert were more than just brothers, they were like best friends, until an unfortunate incident changed their lives forever. Now, their family is scared of losing them.

CLICK HERE to watch what led to the current condition of Daniel and Robert and whether they will find a cure to their troubles or not in the upcoming episode of A&E's "Intervention" Season 15.

The synopsis of the episode, as stated by A&E, reads:

"Brothers Daniel and Robert were on the road to success. Daniel was headed for a career with the NY Yankees and Robert was an aspiring civil engineer. Injury ended a once bright career for Daniel who slid into using pain pills and then heroin to cope.

"The constant insecurity of living in his younger brother's shadow led Robert down the same path. Now the brothers spend their days injecting up to 21 bags of heroin per day – each. It is only a matter of time before this family loses both boys. Jeff Vondernen is the Interventionist."

Whether Jeff Vondernen will succeed in convincing the two brothers to quit drugs and lead a good and healthy life, will be seen only once the episode airs.

The previous episode explored the story of Karissa, a talented cook who once dreamt of running the family diner and maintain her family's legacy. However, things took a drastic turn when a close family friend fed her Oxycodone, and then ultimately made her a drug courier.

From there, Karissa was lost. Years of self-abuse, self-medication and a severe addiction to heroin left her volatile and desperate. Her family feared that if she does not heal from her violent past and the childhood she lost, she will never have the future she deserves. Sylvia Parsons served as Karissa's Interventionist in the episode.
