As manager of the Majestic Hotel, Robert Grant is trained to handle the most chaotic situations with ease. He deftly juggles the needs of his staff, his clients, his two sons, and his cold-hearted boss, Mrs. Dubrow, without breaking a sweat. There's nothing he can't handle. That is, until Dunston checks in. Forced into a life of crime, Dunston is an orangutan and the captive partner of the low-life jewel thief, Lord Rutledge. When Dunston flees his malevolent master, he quickly turns a five-star hotel into a three-ring circus. Joining Dunston in his madcap antics is Robert's young son, Kyle, who rescues the young orangutan from Lord Rutledge. Together, Dunston and Kyle make some merry mischief in the glamorous hostelry, much to the chagrin of the hotel's frantic staff and befuddled guests, as well as a determined but inept animal control officer named La Farge.
