Unleashed

Bart runs a vicious debt-collection operation in Glasgow, using Danny as his enforcer. Danny is trained to be an attack dog, with a heavy metal collar that Bart uses to control him. The collar keeps Danny docile and unobservant, but its grip begins to falter as its limitations become apparent. The tension hints at a chance for change.

Bart is invited to an underground death-match ring with a hefty prize if Danny can survive monthly bouts. Danny enters the ring and easily wins his first match, showing his raw power. The win marks the start of Bart's plan to monetize Danny through brutal fights.

Bart's misstep with a rival mob ends in a shootout that leaves Bart for dead. Danny survives the confrontation but is badly injured and collapses at an antiques warehouse. A blind piano tuner named Sam finds him and carries him to his home to begin his recovery.

Sam and his stepdaughter Victoria nurse Danny back to health at Sam's home. Victoria removes the collar, symbolizing a new level of trust and freedom. Danny slowly reconnects with music and unravels fading memories of his mother as he heals.

As Danny regains his humanity, he becomes curious about music and starts piecing together his past. He recalls glimpses of his mother, which begin to shape his identity beyond violence. The nurturing environment deepens his transformation.

Weeks later, Sam informs Danny that they are moving back to New York, the city where he and Victoria are from, and invites Danny to join as family. Danny accepts, hoping for a fresh start away from Bart. The trio prepares for a new life beyond Glasgow.

While out shopping, Danny runs into Lefty, Bart's right-hand man, who confirms that Bart is alive and plotting his next move. Lefty escorts Danny back to Bart, and Bart pushes him toward the underground ring for the next fight. Danny steels himself for what comes next as he confronts his past.

Danny faces four opponents in rapid succession. He overcomes them with skill, but refuses to kill, signaling a fundamental shift from Bart's expectations. Bart grows furious and tightens his hold on Danny's fate.

Bart drags Danny back to his compound and locks him away, but Danny escapes and searches through Bart's old photographs. He discovers a face resembling his mother, triggering a crucial memory of his past. The revelation fuels his quest to uncover the truth about his family.

With Sam and Victoria's help, Danny uncovers that his mother was a Glasgow music student who offered herself to Bart for funds, hiding baby Danny in a closet. Bart killed her when she defied him, and he has raised Danny ever since. The revelation reshapes Danny's sense of belonging and destiny.

Bart and a gang arrive at Sam's apartment complex to seize Danny. Danny hides Sam and Victoria in their closet and goes out to fight the intruders. He faces Bart and asserts his new identity by refusing to surrender.

Bart tries to persuade Danny to return to his old life, but Danny refuses and delivers a fierce beating. Sam intervenes by smashing a flowerpot on Bart's head, knocking him unconscious. Danny, Sam, and Victoria share a tender embrace, solidifying their new family.

Sometime later, Danny accompanies Sam at a piano recital at Carnegie Hall. Victoria performs the same song from Danny's childhood, triggering a smile in Danny as he savors his new life infused with music and memory.
