Butterfly

Malcolm discovers a man, Norm, living in the Lucky Aide. He agrees to keep Norm's secret as long as he provides Malcolm with tidbits on his new crush, a fellow Lucky Aide employee. Meanwhile, when Reese takes a job as an exterminator, he quickly learns that to drum up business he must infest the neighbors' lawns, and chooses caterpillars as his weapon. But instead of spreading the caterpillars, he has a change of heart and begins to nurture them, ultimately leading to his own menagerie of butterflies.

Andy's world explodes by a seemingly senseless act of violence during a concert shooting. When she sets out to unravel the details, she comes into direct conflict with Luke's former partner, Detective Jo Rosati, a new detective with Division 15. As Rosati investigates the case, sparks begin to fly between her and Luke.

The Butterfly, or Le Papillon in original French, is a film by Philippe Muyl starring Michel Serrault and Claire Bouanich.
