The inaugural episode of "Sexy Beast" kicks off with an intriguing scene: Gal, lounging atop a building, basking in the sunlight, is unexpectedly interrupted by his criminal cohort Don, who approaches him wielding an unloaded shotgun. Despite the ominous weapon, Gal, aware of Don's presence, casually greets him with a nonchalant "Hi Don."
Together with a team of rugged men, Gal and Don embark on a daring heist. The crew storms into an arcade, intimidating both staff and patrons with their brute force, demanding access to the safe. When a staff member claims ignorance of the safe's combination, the gang employs further intimidation tactics, forcing him to divulge the code. With the safe open, they swiftly make off with the cash, leaving behind a message for the owner, conveyed through the trembling staff member, to cease harassing Don's sister.
After their triumphant heist, the group celebrates their success, and Gal's eyes are immediately drawn to Dee Dee, a mesmerizing presence. He invites her to join him, but she plays hard to get, revealing herself to be a renowned adult entertainer. The narrative then shifts to introduce Gal's family and his long-suffering fiancée.
Meanwhile, in the underworld, Teddy Bass, a powerful figure, is plotting another heist. His associate, Stanley Higgins, brings up Gal and Don, acknowledging their growing influence and prowess. We are then introduced to Cecilia, Don's sister, a formidable woman who runs a modest yet thriving casino.
Teddy Bass convenes with Gal and Don at a sleek club, broaching the possibility of them joining his elite team for a high-stakes heist. Gal, partial to their independent operations, is hesitant. However, Don, eager for a more luxurious lifestyle, is all in.
Gal remains irresistibly drawn to Dee Dee, and they delve into a profound conversation. She expresses her belief that life holds greater possibilities and her yearning to flee her present circumstances. Gal confesses to her that he is a thief, asserting that the honest life was never suited for him. Dee Dee reveals her desire to escape to a sunny locale. As they are at her abode, Dee Dee suddenly hears a noise, prompting her to urge Gal to depart. Gal surmises that it could be her husband or boyfriend returning.
Later, Gal and Don converse over the phone, with Gal expressing his intention to participate in a high-risk heist. They meet with Teddy, but Gal insists that they should be equal partners throughout the endeavor. "All in or all out," he declares firmly.
The crew executes a meticulously crafted theft, targeting an armored van transporting a rare coin. Teddy directs them to seize the blue box containing the coin in deposit box number 403. He reveals that the coin is the initial piece of an enormous puzzle. However, the gang encounters an unforeseen issue—a security guard witnessed the crime, posing a significant threat. Teddy demands that no loose ends be left, tasking Gal with eliminating the witness. Cecelia warns Don that if Gal fails to act, he must do it himself.
Gal confronts the security guard, intending to carry out the hit, but Don unexpectedly arrives as well. Gal trains a gun on Don, leading to a tense standoff. Gal asserts that they are not murderers and instead gives the security guard money, instructing him to flee. Don is enraged, but Gal insists that he has saved the guard's life and speeds away from the scene.
The episode concludes with the group celebrating their successful heist over drinks. Teddy joins them to celebrate, but in a startling turn, he shoots and kills Larry, one of the gang members, blaming him for the security guard witnessing the crime. He inquiries with Gal if he has resolved their problem, and Gal confirms that it is taken care of.
