If It's Tuesday, This Must Be Belgium

A group of travelers from the United States embark on a whirlwind 18-day journey through seven European countries, led by the charismatic but somewhat reckless tour guide Charlie Cartwright (Ian McShane). As they explore the continent, various romantic misadventures and unexpected encounters unfold, including a blossoming romance between Charlie and a hesitant Samantha Perkins (Suzanne Pleshette), a chance encounter between a veteran and a widow in Belgium, and a hapless suitor's quest for the perfect cousin in Italy. Along the way, the travelers encounter a cast of eccentric characters, each with their own stories and misadventures.
