Stranger Anniversary is a Hong Kong romantic comedy about two strangers who discover they're perfect doppelgangers through a lookalike website. Ko Sau-shing, a successful law firm partner, reconnects with his former lover Yu Fung online, only to learn she's seeking a part-time boyfriend who resembles her ex. Sau-shing approaches Mo Kei-nam, a deadbeat who could be his twin, and the two impulsively agree to swap identities for two weeks. Sau-shing poses as Yu Fung's substitute boyfriend while Kei-nam takes over Sau-shing's life, navigating his wife, demanding father-in-law, and mounting law firm crises.
