I remember watching this movie about a kid that was really smart and his family is suddenly held captive by a bunch of guys in their own home with guns. His sister was addicted to sex and she seduced one of the bad guys to distract him. The kids name I believe was stewart and he set up traps to nail the bad guys one by one so he could save his family. This movie was in color, it was either a 80s or 90s movie. I remember renting it from blockbuster a lot when I was a kid. it was similar to home alone.
