The Robot Mafia holds up an armored car in space and steals $8 million in cash, but jettisons it into a dumpster on Earth when the police give chase.
Meanwhile, the Planet Express crew takes a vacation to Mars, planning to stay at Leo and Inez Wong's hotel and casino.
On Mars, Amy explains that her parents built their fortune thanks to her ancestor, Sir Reginald Wong, who swindled the native Martians out of their land.
At Planet Express, as the crew recovers from a severe hangover, Professor Farnsworth uses a laser to make the ink in Fry's new facial tattoo invisible.
The crew sneaks Zoidberg into the vault, using a batch of spoiled shrimp from the casino buffet to cover his natural body odor and foil Blind Joe.
Amy retrieves the box and opens it to reveal a document signed by Sir Reginald, which returns the land to its rightful owners (the Martians) after 100 years.
