Suspicions about his girlfriend, Natalie, come to a head when Isaac gets the chance to check her phone just before she leaves for a night out. There’s a shock when he finds a Tinder contact on it, but he says nothing about the fact she may be cheating on him. Her story about meeting one of her friends for a drink suddenly rings hollow though, and he follows her when she leaves to find her meeting her Tinder date in a quiet bar. When a second man appears, his shock grows and he ducks into the dark alley beside the bar when he sees them leaving. That leaves him in prime position to watch the whole thing as he is cuckolded by two men using his girlfriend in a back alley encounter.
