Scene help, script recommendations

This might be weirdly specific, but I'm looking for good scene and script references for the below:

Protagonist returns home, hears laughter filter in from another room. Upon entering the room, they find a family member (wife/daughter/husband) talking to a stranger. But the protagonist knows the stranger, who is potentially dangerous, unbeknowst to the family member.

It's like a secret tension playing under the surface between protag and stranger.

Any good examples I should read? I want to see how other scripts execute the "hidden tension" and covert intrusion.
