Intimate Deception (1997)

Charlie is an artist in a slump. He is constantly harassed by his "step-father-in-law," Bob Masters, about his having shot a burglar in the recent past. When Charlie and Jennifer decide to take in Tina as a boarder she turns out to be a model ready and willing to pose for Charlie and perhaps to offer him bonus services. Meanwhile John the new next door neighbor shows up, needing to borrow a cup of sugar and apparently trying to seduce Jennifer. Is there a way to weave all of these pieces together into a believable plot?
