Ar Fedi 5ed, ychydig ar ôl hanner nos, mae Death-Cast yn galw Mateo Torrez a Rufus Emeterio i roi newyddion ddrwg: maen nhw’n mynd i farw heddiw.

Mae Mateo a Rufus yn ddieithriaid, ond, am wahanol resymau, mae’r ddau yn edrych i wneud ffrind newydd ar eu Dydd Olaf. Y newyddion dda: mae yna ap ar gyfer hynny.

On September 5th, a little after midnight, Death-Cast calls Mateo Torrez and Rufus Emeterio to give them some bad news: they’re going to die today.

Mateo and Rufus are total strangers, but, for different reasons, they’re both looking to make a new friend on their End Day. The good news: there’s an app for that. It’s called the Last Friend, and through it, Rufus and Mateo are about to meet up for one last great adventure – to live a lifetime in a single day.
