Crimson Wedding (2018)

It's a joyous affair. Sandra and William's wedding and the whole family's gathered in her mother's classy restaurant for the event. Even her sister Alice is back from Australia for the occasion. Then tragedy strikes. Mere hours after the ceremony, the bride is found dead at the bottom of a cliff. An accident, suicide, or is it murder? Alice's ex-lover and cop Vincent zeroes in on an uninvited guest, who quickly becomes the prime suspect. Until he too is found dead. Could the murders be linked? The deeper Vincent delves into the family's history, relationships, and collective guilt, the more tortuous the case becomes. Dark secrets buried for too long suggest that all bear their share of the blame.
