2x3 - Poltergeist: The Legacy

Lat one night a large trunk is delivred to the Legacy house. It is addressed to William Sloane who was meant to be visiting his friends there. when opened the trunk is found to be full of old Scottish artifacts. Not long after the trunk has been opened strange things start happening in the house, the light bulbs keep breaking, high pitched sounds can be heard and unusual lights can be seen flying around. What the Legacy team need to work out is whether or not the trunk has anything to do with this or is it just a coincidence that the trunk arrived just before the problems started?
