Stupidity: Peter and Amanda were wealthy enough to buy the 11th floor penthouse for $579,000 but had no security cameras. Also, Det. Martinez never thought to check surveillance cameras outside the Wright's penthouse; surely cameras were around and/or the Detective could have questioned neighbors if anyone saw Charles near the penthouses or with the Wright's dog Humphrey. Peter or the detective could have gone near Charles' boat without a warrant and called Humphrey to see if the dog barked in response.

Directed by: Massimiliano Cerchi
Starring: Nicholas Turturro, Krista Grotte Saxon, Vanessa Ore
Genres: Thriller
Plot hole: Charles was a con man, going up the east coast (Florida and North Carolina) offering to do cheap storm repairs, taking the 50% cash down-payment and moving on (fleeing to the next location). As such, he would try to stay away from police/law enforcement officers and not call attention to himself. Filing (bogus) criminal complaints against Peter put Charles in direct contact with the police - a very risky and stupid move on his part.
