Aislinn is an exchange student in London and the life she leads is simple and easy to manage. At least until she meets him... Lina who's Aislinn's best friend becomes homeless as her now ex-Boyfriend kicks her out. Desperate, she asks Aislinn to put her up, which she instantly accepts. But there is one person to hide it from: Lina's brother, who is in London looking for a murderer which remains free. Tall, muscled, cop, grumpy as fuck, he would do anything to take her back to their hometown and obviously make his sister's shitty ex-boyfriend regret. Too bad for him, once he discovers it he'll find an obstacle: Aislinn. But she is already troubled enough with this secret admirer who turns out to be a real psychopath. An eternal conflict, which is not that eternal since the tension between them grows bigger and bigger...
