Impulse

Trying to spice up her husband's sex life, a beautiful married woman finds that she's bitten off more than she can chew.

Trying to put the spark back in their relationship, Claire Dennison (Willa Ford) comes up with a role-playing game that she hopes her husband Jonathan (Angus MacFadyen) will find exciting.

On the night, Claire is so enthralled with her husband's new-found passion that she doesn't realise 'Jonathan' is actually a stranger who bears an uncanny resemblance to her partner.

Discovering the truth and attempting to end the affair, she soon realises her problems are only just beginning when the stranger's psychopathic tendencies emerge.
