Trapped (2002) on Netflix

Four times already, criminal mastermind Hickey and his lover Cheryl have abducted a rich doctor's child, guarded by dumb dogsbody Marvin, and smoothly collected ransom within 24 hours without any fuss. Now it's to be brilliant medical inventor Will Jennings's daughter Abby's turn. But when mother Karen points out the child needs asthma medication and Will uses his skills on Cheryl, the smooth script degenerates into panic improvisation, dangerous for all.
