Het is die tijd van het jaar: trouwseizoen. Een gevreesd en geliefd onderdeel van het volwassen leven. Tijdens een hectische zomer die neerkomt op ongeveer één bruiloft per weekend, maken de twee afgematte studievrienden Ben en Alice een pact om de aanval samen te overleven. Terwijl ze zich toast na toast door de bruiloften van pasgetrouwde vrienden en familie slepen, waaronder die van Ben's vader, struinen ze de tafels af op zoek naar eenzame metgezellen, of op zijn minst wat afleiding.
Nee, helaas is Plus One nog niet beschikbaar op Netflix in Nederland.
