Confined plot
Architect Victoria Peyton is shocked to see 'Help' written in her neighbor's basement window from her window. She rushes to the house and meets Fritz Allen, a loving grandfather who apparently is hiding something behind his smile. Over the next few days, she sees more strange things happening. When she searches for him on the internet, she discovers that Fritz's son has been missing for 16 years and that his wife Bea's daughter is also missing. Veronica, armed with the blueprints of the house under her arm, decides to break in to find out exactly what is going on in the house.
