Catalina Martín is in a bind—she urgently needs a date for her sister's wedding, thanks to a little white lie about an American boyfriend that has spiraled out of control. With everyone she knows, including her ex and his fiancée, expecting to meet him, Catalina has only four weeks to find someone willing to cross the Atlantic and play along with her charade. The challenge is no small feat, especially considering her lively family won't be easy to deceive.

Enter Aaron Blackford, Catalina's tall, handsome, and somewhat condescending colleague, who surprisingly offers to be her stand-in boyfriend. Despite finding Aaron aggravating, blood-boiling, and insufferable, Catalina is desperate and, as the wedding approaches, begins to see him as her best option. She discovers that Aaron might not be as terrible in the real world as he is in the office.

In a moment where Aaron's usual coldness subsides, he expresses gratitude to Catalina's friend Rosie. However, his demeanor remains less grim when dealing with Rosie than with Catalina. As tensions rise, Catalina feels the heat rushing through her body, especially when Aaron requests her to turn around and face him directly, adding a layer of complexity to their unfolding story.
