Back from their first turn in Mario & Luigi: Superstar Saga, the bros. are jumping into a time-traveling, role-playing adventure with a lot of help from their younger selves.

Professor E. Gadd has just completed his time machine! So excited was Princess Peach about the new invention, that she decided to go on a joy ride with a few of her courtiers. But when the time machine returns, no Princess, just an ugly Junior Shrooboid with a taste for Italian plumbers. That's where Mario and Luigi come in. Bidden by Toadsworth, Peach's father, to find his daughter, the bros. travel to the Mushroom Kingdom of yesteryear by jumping through mysterious time holes which suddenly appear.

When Mario and Luigi find themselves in the past, they discover their home been invaded by the creepy Shroobs, an evil alien race jealous of the Mushroom Kingdom's riches. It's up to the bros, child and adult, to save the Mushroom Kingdom, rescue Peach, and return the Crystal Star shards to Prof. E. Gadd.
