Joy Wilkinson’s debut feature, "7 Keys," promises an explosive entry reminiscent of the erotic thrillers of the 80s and 90s. But alas, the plot veers towards the predictable, failing to capitalize on its initial potential. Despite this, actors Emma McDonald and Billy Postlethwaite manage to deliver captivating performances, an alluring beacon amidst script shortcomings.

"7 Keys," first screened in the Visions section at SXSW, has potential to find its spot in streaming platforms, and maybe draw attention from casting agencies looking to scout new talent.

Prior to "7 Keys," McDonald and Postlethwaite had featured in Wilkinson’s short film, The Everlasting Club. McDonald’s earlier roles include a performance in "Layla," while Postlethwaite, son of the late Pete Postlethwaite, featured in "Indiana Jones and the Dial of Destiny" and had minor roles in prominent British TV series like "Midsomer Murders" and "Game of Thrones." More recently, he's taken on recurring roles in series such as "Beforeigners," "Silo," and "The Winter King."

In "7 Keys," the plot’s early unpredictability is its advantage, spurred by the actors' relatively unrecognized status. The intrigue begins with Lena (McDonald) preparing for a night out, with expectations veering towards her being the focal character. Post an unexpected flirtation with computer expert Daniel (Postlethwaite), Lena notices Daniel's huge collection of front door keys from all his previous London residences. A thrilling plan to sneak into these vacant homes, under the guise of a bank holiday weekend, starts to unfold.

However, the film takes a predictable path by revealing hidden identities. But before the plot stumbles, the lively chemistry between the actors and the meticulous detailing of the invaded apartments by production and costume designer Natasha Jenkins stand out as poignant elements. Despite its disconnect with London’s geographical specifics, "7 Keys" encapsulates London’s diversity.

Regrettably, "7 Keys" dismisses the opportunity to explore intricate socio-political themes. Unlike Kim Ki-duk’s 3-Iron, which delves into class struggle, voyeurism and desire via a similar plot, "7 Keys" retreats into a shallow narrative about the perils of sexual relationships.
