Previously ... on Grand Theft Auto V ... There's a slow burn as this game gets to the point of why three characters as disparate as Michael, Trevor and Franklin would or should come together to pull off some astounding heists. That's where the good ol' Lore in a Minute series comes in to help.
I suppose this video should get a spoiler alert, although the details it divulges are either background in nature or occur early in the game. That said, if you're still fooling around in GTA Online and haven't taken much time to explore the story (raises hand) this could ruin a few surprises for you.
