In the seventh episode of "Cashero," the story unfolds with a chaotic series of events that push the characters to their limits. Sang-ung, with a plan in mind, distracts the security while Ho-in sneaks into the vault. Meanwhile, Eun-mi brings in Anna's men, only to be met with a fierce battle against Gimhae's security forces.

The trio, Ho-in, Eun-mi, and Sang-ung, regroup in the vault, only to find themselves facing off against Su-yeon and Nathan's men. In a desperate move, Ho-in pushes Sang-ung into another room where he discovers Won-do's stash of money. Using this as leverage, Sang-ung fights off Nathan's men and So-yeon while Ho-in and Eun-mi escape to safety. However, Nathan remains standing, but before Sang-ung can take him down, his powers suddenly stop working. He faints and wakes up in Hwang's car, powerless and disoriented.
Hwang advises him to stay out of trouble, reminding him that using other people's money has caused his powers to fade. Sang-ung shares his theory that Nathan is planning to sell pills that grant temporary superpowers, but Hwang dismisses it, stating that bad guys have always done evil things and it's not Sang-ung's job to stop them. As they disperse, Anna arrives and secures the ampoules. But her plans are foiled by Jeong-ja and her men who overpower her and break into a room adjacent to the vault.
Meanwhile, Sang-ung rants to his father about the pointless nature of fighting in a rigged game. Dong-gi counters that money isn't their motivation; once Sang-ung realizes what's truly important, he'll regain his powers. Dong-gi also returns the piggy bank that he had broken out of desperation, proving to be a devoted father once again.
The story reaches a climax when Won-do, furious with Nathan for his failure, books him out of the country. However, they are interrupted by Jeong-ja who reveals she has found a ledger from Gimhae Bank containing the capital amount Won-do's father borrowed from Jeong-ja's father to start their empire. Jeong-ja demands her money back and takes all the money stashed in the bank.
The episode ends with a sense of uncertainty and anticipation for what lies ahead in the world of "Cashero." The characters' struggles and motivations are further explored as they navigate through this complex web of power and betrayal.
As Won-do's attention is diverted, Nathan seizes the opportunity to kidnap Min-suk, threatening to end her life unless Sang-ung complies with his demands. Min-suk's unwavering belief in Sang-ung, refusing to be intimidated, stings Nathan's pride. Meanwhile, at the precinct, Hwang gazes at his broken watch, reflecting on Sang-ung's collapse just before the arrival of the police at the bank. He shares with his colleagues that time is more valuable than money and that Sang-ung is innocent of any crime.
Elsewhere, So-yeon presents a challenge to Sang-ung, revealing that he is useless without his powers. However, if he can defeat her, she will lead him to Min-suk. Unfortunately, his powers remain dormant, and she effortlessly defeats him. Eun-mi and Ho-in intervene, knocking her unconscious to save him.
Ho-in divulges that Min-suk is being held captive at Beomha Logistics, a seemingly impregnable fortress. He suggests devising a meticulous plan, but Sang-ung, unwilling to wait, decides to act immediately, not wanting to risk Min-suk's life.
The following day, Sang-ung embarks on a solo mission to Beomha Logistics. It is then that he fully comprehends his father's mindset - that protecting someone and fighting for what's right is more significant than material wealth. With a newfound resolve, he leaps from the rooftop of the building.
