This starts out as a neat psycho-thriller, but managed to stretch my credibility beyond the breaking point. No spoilers, but…
A criminal, John Taylor, is on the lam from a bank job; his task is complicated by the fact that the cops are everywhere, and he's been shot in the foot. Looking for refuge, he glibly talks his way into a nice home inhabited by—hey, it's Niles Crane! No, actually, it's Warwick Wilson, played by David Hyde-Pierce.
Warwick is a gracious host, and seemingly duped by John's impersonation of a friend of a friend. He invites John to stay for a dinner party later that night. But it gradually becomes apparent that Warwick was not fooled, and he has other, more sinister, plans for John.
Helen Reddy is in this, by the way. Yes, that Helen Reddy: "Delta Dawn", "I Am Woman, Hear Me Roar". According to IMDB, this is her first movie since 1987. I didn't recognize her.
