Dr David Barrow, a psychiatrist haunted by his past, is drawn into a web of mystery when he meets the captivating Lola — a reckless, magnetic stranger who turns a chance encounter on the London Underground into something he can't explain or forget. But Lola is not who she claims to be. She is playing a game of her own. When David's estranged wife Helen is found dead under suspicious circumstances, his search for answers leads him straight back to Lola — and to the buried darkness inside a corrupt rehab clinic that connects them both. As David digs deeper, he must face a chilling possibility: the woman he just met holds the key to everything — Helen's death, his own fractured history, and a truth that could either save or destroy them both. Pathological is a gripping psychological thriller of deception, shifting identities, and treacherous lies — packed with twists that will leave you questioning what is real until the very last page. Some lies can't be untangled. Some truths are too dangerous to uncover.
