Episode 8 of "Sexy Beast" kicks off with a nostalgic flashback, depicting Teddy Bass indulging in a sexual encounter with a wealthy, elderly gentleman, while, in a dark twist, another individual chokes a woman amidst a twisted sexual game, silencing her permanently. Shifting to the present, Bonfire Night ignites the skies, and Teddy Bass unwinds with a sip of wine, as Gal and Don venture into their daring heist. The sound of drills echoes incessantly, yet Hal grapples with the aftermath of his stabbing wound from Marjorie's stiletto heel in the previous episode.
Elsewhere, chaos erupts as Freddie McGraw storms Teddy's club, unleashing a hail of bullets from his machine gun. Teddy, quick on the draw, retaliates, hitting two of Freddie's cronies. With calm authority, Teddy orders the patrons to evacuate while advancing towards Freddie, firing shots that leave him wounded but alive. Seeing a potential use for him, Teddy spares Freddie's life, allowing him to limp away, gravely injured.
Gal, meanwhile, manages to crack open the vault and secure the glittering diamond, initiating their escape. However, Gal is injured, forcing Don to physically drag him to safety, narrowly escaping capture. Gal's mother, concerned for her son's well-being, visits Dee Dee, pleading with her to desist from meddling in Gal's affairs. Marjorie, torn apart by the ordeal, threatens to expose Gal's theft of her father's wealth to the police, a revelation she shares with Ann Marie, who remains steadfast in her loyalty to Gal and warns Marjorie to desist.
Later, Gal and Don make their entrance at Teddy's club, where they revel in the triumph of their heist. Teddy, impressed by Gal's prowess, demands the diamond. Regarding payment, Teddy enigmatically teases, "All will be unveiled in good time."
Teddy convenes a meeting with Eaton, presenting the glittering diamond with a proposition that shines even brighter: McGraw's vast territories and substantial assets, all in exchange for this priceless gem. This lucrative offer leads Gal and Don to the entrance of an exclusive club, where, quite coincidentally, Gal recognizes the very spot where his fateful encounter with Dee Dee first unfolded.
Inside the club's opulent interior, Teddy welcomes them warmly, declaring the venue theirs for the taking, a playground of endless possibilities. The trio stands at a crossroads, torn between seizing this golden opportunity and hesitation. Gal, less enthusiastic than his counterpart Don, seeks a brief reprieve, inquiring whether they might have a single day to ponder over their decision, to weigh the pros and cons with clarity.
Teddy, understanding their dilemma, grants them this indulgence, his tone urging them not to linger too long in indecision but to act swiftly when their minds are made.
Don confides in Cecilia about the tempting offer, but her reaction is anything but jubilant. Her fury escalates into blows, prompting Don to retaliate, inadvertently causing her to strike her head and perish.
Elsewhere, Gal reconnects with Dee Dee, but their reunion is abruptly shattered when a passing vehicle douses her with acid. Gal hastily rushes her to the hospital, where she lies recovering, her beauty marred by scars. As he keeps vigil at her bedside, Dee Dee confesses her heartbreak over her cinema dreams dashed and their relationship's impossible future. She implores him to leave, unable to bear the sight of him amidst her despair. Devastated, Gal exits the hospital, his heart heavy.
The episode concludes with Teddy dialing Roger Riley, his accomplice from the heist, now residing in Spain. As they converse, a chilling command from Teddy leads to Riley being stabbed, his lifeless body plunging into the swimming pool. Eaton, riding shotgun, confirms the grim task is completed.
After much reflection, Gal and Don ultimately decide to decline Teddy's offer for the club, their resolve hardened by the tumultuous events that have unfolded.
