Totally Spies! (2002)

Season 5: Episode 16

Concerned about their friend, Alex and Clover decide that the only way to find out what's wrong with Sam is to spy on her! But what will happen when they find that Sam is involved in some shady activities? They find out Sam is going undercover as a villain, even teaming up with Jazz Hands (just to defeat him, of course). In a b-story, Mandy and Mindy move in to the girls' penthouse when a pipe in their dorm room breaks.
