Regular Show Movie is the movie of Regular Show Adventures. This movie follows Mordecai, Rigby, Wally, Thomas, Benson, Skips, Pops, Muscle Man, and High-Five Ghost going on an extremely long roadtrip to visit Thomas' dad for Thanksgiving, an allusion to the John Hughes film Planes, Trains and Automobiles.
The movie starts in the park with Mordecai, Rigby, and Wally eating pizza. Benson calls them to Skips' house for a meeting. At Skips' house, Benson tells the workers that the park's annual Thanksgiving celebration is coming up. He asks everyone for ideas, but no one suggests. Thomas then raises his hand, and Benson calls on him. Thomas mentions his dad called him over for Thanksgiving. Thomas then asks everyone if they would like to come over to Thomas' home in Rhode Island. Everyone agrees, and we cut to a montage of them packing up things for the long trip.
However, their flight from LaGuardia Airport to O'Hare is diverted to Wichita due to a blizzard in Rhode Island, which ends up dissipating only a few hours after touchdown in Kansas. When every mode of transport (including a train and a rental car) fails them, what should have been an 1 hour and 45 minute Park-to-Rhode Island flight turns into a three-day adventure. To complicate matters even further, on the first night in Wichita, a thief breaks into the poorly-locked motel and steals almost $1,000 aggregate from the guys.
Wally frequently blows up at Benson, blaming him for much of their misfortunes, including the robbery of the first night. These ravings are not all unjustified, as HFG's carelessly discarded cigarette sets fire to the rental car, melting all but the radio. Mordecai in turn regards Rigby as a pretentious and uptight cynic while Pops is less afraid to be himself. After a much heated argument between the workers, a bond between them forms, and Mordecai finally manages to overcome his arrogance. The boys pull together to finally make their way home, while Skips manages to raise money by selling off his entire inventory of shower curtain rings, to kids and adults alike, who think they make good earrings.
Under the assumption that HFG has a wife and family of his own (he frequently mentions his wife Marie and puts a framed picture of her on his various motel nightstands), he and Muscle Man part ways. However, Muscle Man later pieces together things Benson said and realizes that HFG is alone. The guys go back to the train station where he had left HFG and sees him sitting alone, inside an empty station, after they finally make it to Rhode Island. HFG tells the crew that Marie actually died eight years prior and that he has been homeless ever since. Thomas, having become a nicer person during the journey, invites the crew to enjoy Thanksgiving with his father.
