Given the question: Build a movie plot around this: Why is Doorbal impotent? Doorbal became impotent due to his use of steroids.
The answer is:
In 1995, schemer Daniel Lugo (Mark Wahlberg) is a recently released convict who had served time for Medicare fraud. Sun Gym owner John Mese (Rob Corddry) hires him to increase membership and make the gym more fitness-based. Lugo increases the gym's membership by 75% within six weeks and befriends trainer Adrian Doorbal (Anthony Mackie), a bodybuilder rendered impotent due to his steroid use. Lugo soon lusts after the earnings and lifestyle achieved by Victor Kershaw (Tony Shalhoub), a sleazy, new gym member he begins to train, who Lugo believes is a crook. Inspired by motivational speaker Johnny Wu (Ken Jeong), Lugo decides to be a "do-er" and hatches a plan to extort Kershaw for his assets by kidnapping and torturing him.Lugo recruits accomplices Doorbal and Paul Doyle (Dwayne Johnson), a recently released, cocaine-addicted convict who has turned to Christianity. Though Doyle is reluctant to join the team, he soon acquiesces after a violent altercation with his priest. This "Sun Gym gang" unsuccessfully attempts to kidnap Kershaw at home, and a second time in public, but later incapacitates him with a taser outside his deli and takes him to a small warehouse he owns (which is stocked with sex toys). The kidnappers wear masks and Lugo disguises his voice, but Kershaw identifies Lugo from his distinctive cologne. The scheme goes as planned otherwise: Kershaw makes calls, under duress, to provide false explanations for his disappearance, gets his family to move out of state, and signs the documents that transfer his assets to Lugo. Lugo even bribes John Mese to notarize documents in Kershaw's absence, by presenting documents signed by Kershaw and using Kershaw's money to sponsor the Sun Gym.The Sun Gym gang is able to collect Kershaw's money and assets, but they realize releasing him is a bad idea. Therefore, Lugo concocts a plan to kill Kershaw by forcing him to drink liquor and crash his BMW, making it appear like a drunk driving accident. When Kershaw survives the crash, the gang burns the car with Kershaw...
