While Angela is sleeping, a couple of thieves sneak into her house and steal her most treasured possession - a valuable antique vacuum cleaner. Old Tom, however, sees them and hides in the back of their getaway truck, leaving a trail of sweetie wrappers behind him. When the thieves unload the stolen goods into their warehouse, they unknowingly unload Old Tom, too. Meanwhile, Angela wakes up and discovers that her vacuum cleaner - and Old Tom - are missing. With a policeman's help, she follows the trail to the warehouse, where Old Tom catches the thieves and hands them over to the policeman.
